[New-bugs-announce] [issue41214] -O0: Segmentation fault in _PyArg_UnpackStack

[Vincent LE GARREC]

New submission from Vincent LE GARREC <legarrec.vincent at gmail.com>:

In Gentoo, I compile my system with -O0

When I compile Apache Serf, python 3.7.8 crashes. When I compile python 3.7 with -O2, python don't crash when compiling Serf.

It's the first time that -O0 causes program crash.

I run test suite, I don't have any problem.

Please find enclosed the backtrace.

I can reproduce every time so if you want me to do some tests, I can do it.

I already report it to Gentoo (https://bugs.gentoo.org/730312) but it seems it's not related to them.
