[Bug 53032] winedevice.exe segfaults on exit when built by GCC >=12.0 and -march=pentium-m

[WineHQ Bugzilla]

https://bugs.winehq.org/show_bug.cgi?id=53032

--- Comment #21 from Bernhard Übelacker <bernhardu at mailbox.org> ---
This seems to be a more reliable callstack without the gdbinit.py magic,
but instead just loading the loader/wine executable.

I guess the important line is the free_delay_imports frame.
As this is a non-PE build, might this stack get damaged by the
stack unwinding - and therefore the wine call is no longer working?


Following is all from one thread, just before the segfault:

What I do not yet understand why the free_delay_imports
seems not to get called at all at my usual Debian system.
