[issue37720] Crash of python3.7 with virt-manager

[STINNER Victor]

Try to run virt-manager with faulthandler enabled to get the Python traceback where the bug occurs:

PYTHONDEVMODE=1 virt-manager --no-fork

I expect that the bug comes from a third-party C extension (no part of Python standard library). My notes to debug a Python crash:
