So I've managed to find a recent Xeon server with Windows VM and I see the compile errors you describe on it too. Doing make clean ./configure --extra-cflags="-fno-asynchronous-unwind-tables" make -j fixes the "invalid register for .seh_savexmm" error for me. Another workaround is to disable the generation of problematic AVX instructions: make clean ./configure --extra-cflags="-mno-avx512f" make -j but the binary made might be ever so slightly slower (and you'd need incredibly fast disks and when I did a quick check with the null ioengine I actually found the non-AVX512 version of fio was faster in my VM...). It looks like this is the "gcc/mingw-gcc fails to align the stack properly to Windows' requirements when using AVX 512 instructions" issue: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=65782 https://gcc.gnu.org/bugzilla/show_bug.cgi?id=54412 https://stackoverflow.com/questions/30928265/mingw64-is-incapable-of-32-byte-stack-alignment-required-for-avx-on-windows-x64 https://stackoverflow.com/questions/43152633/invalid-register-for-seh-savexmm-in-cygwin -- Sitsofe | http://sucs.org/~sits/
