3.15.0b2, openSUSE/Factory, i586: failing test: test_c_stack_unwind (specifically test_manual_unwind_finds_expected_frames)

Bug report

Bug description:

As a followup to https://github.com/python/cpython/issues/151040 I am creating this separate ticket for i586. The traceback is exactly the same:

@vstinner on the other ticket commented:

That's a different architecture. If you care, you should open a separated issue for i586. You pass explicitly -fomit-frame-pointer which goes against PEP 831 (approved in Python 3.15).

Yes, we have -fomit-frame-pointer specifically for i586 architecture.

CPython versions tested on:

3.15

Commencez par Lib/test/test_c_stack_unwind.py, en particulier ManualStackUnwindTests.test_manual_unwind_finds_expected_frames vers la ligne 285, et reproduisez l’échec sur i586 en utilisant le openSUSE python315 package build. Examinez le journal de compilation et le paramètre explicite -fomit-frame-pointer en relation avec PEP 831. C’est terminé lorsque le test en échec réussit de manière fiable sur i586 ou que la limitation de la plateforme est documentée avec un résultat de test approprié.
