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
