File that crashed my patched MinGW
I tried to compile Wine 8.21 with GCC 12 plus the patch from comment #5 and
-march=native on a Ryzen 7800X3D, but MinGW crashed with:
i686-w64-mingw32-gcc -c -o libs/tiff/i386-windows/libtiff/tif_aux.o
libs/tiff/libtiff/tif_aux.c -Ilibs/tiff -Iinclude -Iinclude/msvcrt \
-Ilibs/tiff/libtiff -Ilibs/jpeg -Ilibs/zlib -D_UCRT -DFAR= -DZ_SOLO
-D__WINE_PE_BUILD \
-fno-strict-aliasing -Wno-packed-not-aligned -fno-omit-frame-pointer
-march=native -freport-bug
during RTL pass: split1
libs/tiff/libtiff/tif_aux.c: In function ‘_TIFFUInt64ToFloat’:

Omitting -march=native or using unpatched GCC avoids the compiler crash.
I used GCC 12 because unfortunately, Arch Linux does not yet have packaging for
GCC 13, and compiling MinGW without the help of a PKGBUILD file looked pretty
daunting. If you want to try it yourself, just clone
https://gitlab.winehq.org/wine/wine.git and run `./configure
CROSSCFLAGS='-march=native' && make -j16`.
