build log: https://dev.gentoo.org/~fordfrog/chromium-build.log.bz2 (too bit to attach)
_mm256_min_epi32 is an AVX2 instruction. I guess: > gcc -c -Q -march=native --help=target on your system prints: -mavx2 [disabled] Probably detection is wrong, because I build with -march=x86-64.
Can confirm having this same problem. I experience it with Chromium 95.0.4638.32 but not with 95.0.4638.17. Tried with GCC 11.2 and 10.3, same result. I have a Sandy Bridge-E CPU which supports AVX but not AVX2.

Reproduced with -march=ivybridge. The problem is in third_party/eigen3/src/Eigen/src/Core/arch/AVX/PacketMath.h There we have one function without AVX emulation: template<> EIGEN_STRONG_INLINE Packet8i pmin<Packet8i>(const Packet8i& a, const Packet8i& b) { return _mm256_min_epi32(a, b); } Workaround is to compile Chromium with -march=x86-64 for the moment.
Created attachment 742812 [details, diff] patch Attached patch fixes it for me. Can someone test as well? Eigen GitLab Repo is down at the moment. Maybe it was fixed there already.
