Build crashes when trying to build C code. I`ve tried to build it with normal -O2 -pipe flags and with -O3 with lto flags and with gcc and llvm. Also tried with MAKEOPTS="-j1" just in case Reproducible: Always Steps to Reproduce: 1. emerge --oneshot --verbose =dev-python/zstandard-0.23.0 Actual Results: Build crashes Expected Results: Build
