To be clear:
- you did not provide anything for us to test.
- the fact that the crash is inside python31.dll does not indicates a
bug in python.
Consider this (bogus) code:
     FILE *fp = fopen("c:/temp/t", "w");
     free(fp);
This will lead to a crash at program exit (when fcloseall() is called
by the system)
but the issue is really in the code - it should not free(fp).

Without knowing what your code really do, we won't be able to help.
