Since it involves changes in the C++ source code, you would need to apply said changes to the source (either through something like git-apply, or by following
these instructions) and then compile the DLL yourself (possibly by following
these instructions).
If recompiling the DLL is outside your skill-set, you will have to wait for someone else to do it. Presumably, a version 2.71 will be released at some point.
Alternatively, you could go back to version 2.63 (which does not have this particular bug), although that has its own set of slightly annoying bugs.
