Crash to desktop, with recurring error code in .dmp file

Re-loader · Sep 24, 2022

I'm playing LoR(Legends of Revolution) with dave_uk modmod, on Ghenghis Kai Giant Earth Map, which requires an addition to Civ4WorldInfo.xml to facilitate the larger map.

Here is the results from the .dmp file

Spoiler :

It seems to refer to this line(4941) from CvCity.cpp in the BTS CvGameCoreDLL folder

Spoiler :

If I had to guess, it might have something to do with ownership of a city? City flipping through Culture is enabled, and I have some weak AI cities on my borders. In normal BTS, you are sometimes offered the chance to take over or disband an AI city that flips to you. In LoR there are a few more options and outcomes, such as rebels. I might well be wrong as to the cause of the exception/crash though.

Are there any more types of log I can generate to try to understand this crash??

Did you compile a debug DLL to get this dmp? Seems that debug symbols are available: SYMBOL_NAME: CvGameCoreDLL!CvCity::plot+0
If you have a debug DLL and Visual Studio, then it shouldn't take much extra effort to attach the debugger (see screenshot), which will provide the call stack for the crash.

Sounds like it could be a use-after-free issue. When a city changes owners, the city is copied into a new CvCity instance and the old one gets destroyed. Perhaps the plot function is called on the destroyed instance.

I used WinDbg Preview to read the dmp file.
I have been able to dodge and avoid the crash by luck. I think there is a small random element to the outcome of cities with potential for change of ownership. But the crash has happened 3 or 4 times now so I know it can come back.

What can I do with a debug DLL? Do I need to get Visual Studio?

f1rpo · Sep 25, 2022

Pseudo-random numbers should be reproducible - unless you have the New Random Seed option enabled (or unless the mod uses an RNG whose state doesn't get saved). But accessing the plot coordinates of a destroyed city (through a dangling pointer) may sometimes still find the correct data and sometimes nonsensical data that causes a crash.

I don't think dave_uk's DLL has debug symbols, the file is too small for that, so I don't really understand how the dmp file can indicate which function has crashed. In any case, to reproduce the crash with a debugger attached – and to see what causes the CvCity::plot call – Visual Studio would be needed; I don't think anyone has gotten a different debugger to work. However, a crash that isn't reliably reproducible could be difficult to reproduce at all with a debugger attached. Maybe it's worth enabling autolog.txt (Logging tab of the BUG menu) before delving into DLL modding. If the crash is indeed caused by a culture flip, then a change in city ownership might get logged just before the crash. Could also try inserting print statements in the Revolution Python code that deals with city flipping.

So I run VS with the game and reproduce the crash. VS and the autolog will possibly provide some info?

f1rpo · Sep 26, 2022

To illustrate –

Spoiler :

I've attached my project files for dave_uk's DLL to this post (2nd attachment). With those files, VS 2010 from the easiest-way-to-compile thread and the Microsoft dependencies, one just needs to edit Makefile.settings,

Spoiler :

(when using VS for this, right-click in Solution Explorer and "open with" is needed; the .settings ending confuses VS; oh, and the CIV4_PATH normally needs to end with CvGameCoreDLL - I've moved my Boost/ Python libraries out of that folder)

select a Debug build config

Spoiler :

and set the path to the EXE (screenshot in my earlier post), then build (F7) and start debugging (F5). I was going to introduce an error into the source code for demonstration, but it turned out that I ran into two existing issues while debugging; that's good enough. So, during AI Auto Play, I got this failed runtime check:

Spoiler :

These checks are only made in debug builds (through the /RTC compiler option). The issue, introduced by dave_uk, is straightforward: the variable lacks an initial value and could therefore have any value at runtime. Bugfix:

Spoiler :

I continue debugging (F5) and get a failed assertion a few turns later:

Spoiler :

Assertions are only checked in builds that set the FASSERT_ENABLE flag, i.e. not in release builds. The call stack and local variables show that a unit at plot (39, 26) is attempting to move to that same plot, apparently as part of the combat resolution procedure.

Spoiler :

Arguably harmless in itself, but hints at a problem. (And even entirely harmless failed assertions should generally be addressed in some way because they distract from other failed assertions.) In this case, it seems that the unit's attack plot was set to its own plot at some earlier point that is no longer on the call stack. So I set a breakpoint and load an earlier savegame to reproduce the issue:

Spoiler :

But it turns out that it's not reproducible. There is a Barbarian move from (40, 25) to (39, 26), ...

Spoiler :

... but that's OK, and the assertion doesn't fail this time. I'm aware of some issues with autosaves created during AI Auto Play, so this is not too surprising. Maybe one could reproduce it by starting over from the turn-0 autosave, but I haven't bothered to do that. The assertion had failed on the very turn that AI Auto Play ended, which suggests that the original problem is tied to AI Auto Play. Might be a good idea to add FAssert(pNewPlot != plot()); to CvUnit::setAttackPlot to hopefully catch the problem if and when it occurs again.

Enabling Autolog is a separate idea that will require none of the above. You'd just enable the log file, reproduce the crash, check the log file, hope that the last few lines shed some light.

This is PythonDbg.Log from BTS folder, it's big

Spoiler :

Can supply other info if required.

I tried deleting cities I thought were causing problems in WorldBuilder but it didn't make any difference.

Re-loader · Oct 2, 2022

Forgot to mention, some additional info in the .dmp file

Spoiler :

Namely, the Spaceship lines. The following .dmp file is occuring at the same time as the files in my previous post.

f1rpo · Oct 2, 2022

Weird that there's a stack trace in the dmp. While the (original) makefile does specify a program database (pdb) file for release builds

Release_LDFLAGS=/INCREMENTAL:NO /OPT:REF /OPT:ICF /PDB:"$(Release_PDB)" $(GLOBAL_LDFLAGS)

the MSVC03 documentation says that "If /DEBUG is not specified, the /PDB option is ignored," and, also, that if none of the /Z options are specified, the compiler "produces no debugging information." And the makefile uses /Zi only for the debug config.

Perhaps Windows, when creating the dmp, makes use of the names of exported functions that are stored in the DLL. Both functions in the stack trace are exported:

Code:

?plot@CvCity@@QBEPAVCvPlot@@XZ
?getCompletedSpaceshipProjects@CvTeam@@QBEXAAV?$map@W4ProjectTypes@@HU?$less@W4ProjectTypes@@@std@@V?$allocator@U?$pair@$$CBW4ProjectTypes@@H@std@@@3@@std@@@Z

But, then, the DLL exports lots of functions, so those two being exported isn't all that conspicuous. And the EXE does not export any functions, does not contain the string "initCvPythonExtensions" in plain text, and yet the dmp lists initCvPythonExtensions. I've also seen that function in profiler data; something special about that one maybe. :undecide:

Or perhaps WinDbg obtained a pdb file from somewhere. I don't suppose you passed the vc70.pdb that comes with dave_uk's source code to WinDbg? (That file would not match the release DLL.)

In any case, the stack trace is, at best, incomplete. This function (called only by the EXE)

Spoiler :

should not be on the call stack before CvCity::plot because it doesn't - directly or indirectly - call CvCity::plot. If the stack trace isn't entirely bogus, then it seems that compiler optimizations have messed with it. There's also no indication why getCompletedSpaceshipProjects would be involved in a crash in between turns. On the bottom line, I would tend to disregard this stack trace entirely.

Regarding the Autolog, there's turn 1018, then turn 1019. At the start of t1019, you get a bunch of tech and resource trade offers from the AI and issue a lot of city production orders (or maybe automated or queued). Not sure what a "Barbarian Air Assault" is. Then some promotions and the turn is ended. Some cities finish their order. Then, during AI turns, only a few peace treaties are logged. The last AI turn that is evidently reached is that of the Maya. Then the crash, I assume, and then you loaded a save created at the end of t1019 and ended the turn again? I don't know what else to make of the finished production orders being repeated. But this time, none of the AI turns seem to be reached (or they don't sign any treaties this time around). :confused:

Python log, toward the end, only seems to say that the Ottomans have killed workers of player 30. That may have occurred before the peace treaty signed between Maya and Ottomans, assuming that the Maya are player 30.

Nothing to suggest that any of this actually causes the crash. I thought the culture flipping combined with the CvCity::plot in the dmp was a good lead, but I understand that you've already ruled that out by removing the potentially affected cities in WorldBuilder. The logs also don't report any city having been acquired by the human player (though I guess the game could also crash shortly before creating such a log entry).

Could still enable RandLog along with MessageLog in CivilizationIV.ini and check MPLog.txt for the last few random numbers generated before the crash, but it seems unlikely that this will provide any valuable hint. I would advise proper debugging in VS at this point. (If the crash is not reproducible with a debug build, one could still try a debug build with optimizations enabled.)

Re-loader · Oct 3, 2022

Thanks for your reply.
Space victory is disabled. Barb air assault is a unit. I think an AI city within my borders had rebels and were ejected from my territory because I have Great Wall. It's possible the cities are making multiple units, or it crashed in t1018 and I tried it again only for it to crash the next turn.

How do I go about debugging with VS? Shall I start doing some reading on it or is it straightforward?

f1rpo · Oct 3, 2022

If you can compile the debug DLL and launch the mod with the debugger attached, then it'll hopefully just be a matter of taking a look at the Call Stack window when the crash occurs, and maybe to navigate between stack frames via double-click to see the code lines associated with the calls. For getting it to compile and attaching the debugger, my previous posts in this thread might suffice. Other than that, there are the CFC threads about compiling, mainly Leoreth's and Nightinggale's (the two sticky ones not marked as tutorials). I don't think reading Microsoft's documentation about Visual Studio and Visual C++ is necessary.

Re-loader · Oct 4, 2022

I will try what you mention.
I have also located where in the game the problem is. 2 cities of a vassal(my vassal) are having rebel problems. I deleted them and the turn compeleted without a crash. So I could conclude that the crash is caused by the rebel units being spawned.
I will still try your suggestion.

First time using this type of software. Got as far as F7 and got this in the Output:

Spoiler :

So I need to put the Assets folder from the mod in to the CvGameCoreDLL(contains the VS Solution file) folder that is within the BTS SDK folder?

I also made a makefile.settings(that refers to my relevant locations) file that you mention earlier, but not so sure where I am
going to use this.

When I've completed the F7 part, and I F5, I will load the turn that crashes?

f1rpo · Oct 7, 2022

That looks promising. Some players put the source code and project files into their Mods folder, e.g. into \Mods\LoR\CvGameCoreDLL. That way, they have everything in one place. But you can also set an absolute destination path for the DLL (as in the Makefile.settings in one of my screenshots), or even copy the DLL manually (from temp_files\Debug to Mods\LoR\Assets). The Makefile will include the contents of Makefile.settings if a file of that name is found in the same directory as the Makefile:

Code:

!IF [IF NOT EXIST Makefile.settings EXIT 1] != 0
!IF [ECHO CUSTOM_CFLAGS = > Makefile.settings]
!ENDIF
!ENDIF
!include Makefile.settings

If it's not found, then a blank template is created. If your own Makefile.settings isn't already in the same folder as the Makefile, you could move it there, replacing the blank version.

Re-loader said:

Yes, that would be the plan. And hopefully it'll crash, and, if it does, the debugger should break and let you inspect the call stack in the respective window. Or maybe it'll hit a failed assertion before crashing; that would also be helpful.

To verify that the debugger has been attached, i.e. after pressing F5, you could scroll up in the Output window and look for a line that says "Symbols loaded":

need my speed said:
Well, since I am merging a mod with RevDCM, I merged the .xml's manually, and now only need to merge the CvGameCoreDLL.dll's. So while I do not have the original RevDCM files in my mod's folder, I do have the files. Besides that, I already modded RevDCM quite heavily, just only by XML.

I just see, I have copied all the files (as far as I can see) of RevDCM... Maybe that is the problem? I have also made a screenshot to show what I meant with 'missing interface'. Also notice the strange icon that is in front of the message that my Scout has popped a goody hut.

Yes... As I said, the interface...

But it still gives that error, even when I'm using the exact same files of RevDCM, but only with my CvGameCoreDLL.dll.

Also, the game/mod itself won't load and presents the same errors.

The back up of the mod(original LoR without dave uk etc) does load and works fine.
I've looked at the Python folders of both, and they're identical. Not sure what else to look for, and trying to figure out what has happened since using VS Studio.

I'm assuming that your mod had previously been using dave_uk's DLL. And you're getting a CvGameCoreDLL.dll out of Visual Studio (temp_files\Debug) after having compiled dave_uk's source code. That DLL needs to replace dave_uk's DLL (by copying or moving it there manually or by letting Visual Studio and the Makefile doing the copying). Can you then load your mod from the Advanced menu, i.e. without involving Visual Studio and the debugger? I guess you've tried that:

So you have one mod that loads and another that doesn't, and the only difference between them is that one uses dave_uk's original DLL and the other the debug DLL you've compiled?

This is all new territory for me.
I have found the new .dll
I found the dll.log it says the file has been copied.
F7 appears to be successful
F5 now leads to: Debugging information for 'Civ4BeyondSword.exe' cannot be found or does not match. Cannot find or open the PDB file. Do you want to continue debugging?
So I must be missing something obvious? Makefile.settings as far as I know, has the right information/paths
Game won't load from advanced menu.
The mod that loads is "vanilla" LoR without any compiling or modmod. Normal BTS loads also.

This is OK and should be permanently ignored. There is no debugging info for the EXE, just for the DLL.

OK, but the savegame with the crash is, I assume, from your GEM/LoR/dave_uk mod. Does that mod load with dave_uk's original DLL but not with the new debug DLL?

Yes.
I extracted the original DLL from the download file, and it loads fine.
I used the VS .iso linked in the thread you mentioned(Leoreth thread) VS 2010 C++ Express. Am I using the right one? EDIT: Yes, I believe I am.
Do I need identical VS debug config like your first post in this thread, it currently is identical apart from _NO_DEBUG_HEAP=1

Crash to desktop, with recurring error code in .dmp file
