In the Linux musl (Alpine x86_64 3.17 and 3.18.2) build, we run now into a ton of warnings as errors like this :
/usr/lib/gcc/x86_64-alpine-linux-musl/12.2.1/include/avx512fintrin.h:4459:50: error: '__Y' is used uninitialized [-Werror=uninitialized]
Should we disable this warning ? Or is it a problematic warning?
We use gcc 12.2.1 on our Alpine box running Alpine 3.17.4 .
