[New-bugs-announce] [issue41766] Python3.10 (x64) crashes after flake8/pyflakes on Windows

[neonene]

New submission from neonene <nicesalmon at gmail.com>:

On Python3.10(64bit only) for Windows,
flake8 (with .pyc cache) frequently crashes after output.

e.g:
python -m flake8   c:/Python3/Lib/turtle.py
python -m pyflakes c:/Python3/Lib/turtle.py

I think I encountered the crash after PR21293 applied.
(bpo-41194: "Convert _ast extension to PEP 489")
