Please include the complete backtrace with any bug report. See <https://bugs.archlinux.org/> for instructions. Preprocessed source stored into /tmp/cc824MzT.out file, please attach this to your bugreport. make: *** [Makefile:179744: libs/tiff/i386-windows/libtiff/tif_aux.o] Error 1 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`.
