By "the issue", I mean bug.py, not win_py399_crash_reproducer.py.

Victor: perhaps we should open a separate issue for the bug.py issue.

Applying the patch from msg409795 onto the 3.9 branch also fixes the segfault from bug.py there.

main does not segfault for me, but I would apply the patch anyway, since the current code is broken.
