[issue39001] possible problem with 64-bit mingw DECREF

[Dave Lawrence]

Dave Lawrence <mail.dave.lawrence at gmail.com> added the comment:

further investigation seems to point to this being something to do with mingw and the dll. I have tried compiling the same test example on 64-bit linux and in the Ubuntu WSL on windows and it works. Tests also show that the refcount of '1' is correct and not the problem.
the PyObject pointers of 0000000002750408 are suspicious though and on sight look like 32-bit addresses -- is there some odd 32/64 bit mismatch happening somewhere even though the lib clearly links and loads the dll?
