Crash error

I found a slightly weird bug.

When running Deus Ex: Revision mod using regular WineHQ build (for Debian
testing), it crashes during audio initialization [Galaxy Audio]. See attached
screenshot.

But when I compile Wine myself using this set up with explicit CPU architecture
set to znver4:

export CXXFLAGS="-march=znver4"
export CFLAGS="$CXXFLAGS"
export CROSSCFLAGS="$CXXFLAGS"

It doesn't crash. My CPU is AMD Ryzen 9 7950X (Zen 4).

I don't see anything clear in the log output. What can the issue be?

And do you have any suggestions how to get more diagnostic for this?

Build environment:

gcc: 15.2.0
gcc-mingw-w64: 15.2.0

--- Comment #1 from Rafał Mużyło <galtgendo(a)o2.pl> ---
Funny thing, cause for me having '-march=znver1' causes run failures in some
corner cases (I've got a pretty old bug about that, that's effectively a
WONTFIX, cause it's runtime data obfuscator problem).

If this is genuine and someone seriously investigates it, the results might be
somewhat interesting...
