Trying to reproduce this. Don't have a native x86 machine though. In my chroot, I'm using -march=i686 by default, which leads to a successful build. When I swith to -march=native, which you are using as well, the build fails with the same error. Could it be, this is an issue with the march setting, or gcc? When comparing the preprocessor definitions (gcc -dM -E) for both march flags in my chroot, they have quite a few differences, including SIMD #defines not defined with march=i686, although it should have this capabilities (like sse{,2}, mmx). Also (chroot32) # echo "" | gcc -march=i686 -v -E - 2>&1 | grep cc1 /usr/libexec/gcc/i686-pc-linux-gnu/11.3.0/cc1 -E -quiet -v - -march=i686 -dumpbase - (chroot32) # echo "" | gcc -march=native -v -E - 2>&1 | grep cc1 /usr/libexec/gcc/i686-pc-linux-gnu/11.3.0/cc1 -E -quiet -v - -march=znver2 -mmmx -mpopcnt -msse -msse2 -msse3 -mssse3 -msse4.1 -msse4.2 -mavx -mavx2 -msse4a -mno-fma4 -mno-xop -mfma -mno-avx512f -mbmi -mbmi2 -maes -mpclmul -mno-avx512vl -mno-avx512bw -mno-avx512dq -mno-avx512cd -mno-avx512er -mno-avx512pf -mno-avx512vbmi -mno-avx512ifma -mno-avx5124vnniw -mno-avx5124fmaps -mno-avx512vpopcntdq -mno-avx512vbmi2 -mno-gfni -mno-vpclmulqdq -mno-avx512vnni -mno-avx512bitalg -mno-avx512bf16 -mno-avx512vp2intersect -mno-3dnow -madx -mabm -mno-cldemote -mclflushopt -mclwb -mclzero -mcx16 -mno-enqcmd -mf16c -mfsgsbase -mfxsr -mno-hle -msahf -mno-lwp -mlzcnt -mmovbe -mno-movdir64b -mno-movdiri -mmwaitx -mno-pconfig -mno-pku -mno-prefetchwt1 -mprfchw -mno-ptwrite -mrdpid -mrdrnd -mrdseed -mno-rtm -mno-serialize -mno-sgx -msha -mno-shstk -mno-tbm -mno-tsxldtrk -mno-vaes -mno-waitpkg -mwbnoinvd -mxsave -mxsavec -mxsaveopt -mxsaves -mno-amx-tile -mno-amx-int8 -mno-amx-bf16 -mno-uintr -mno-hreset -mno-kl -mno-widekl -mno-avxvnni --param l1-cache-size=32 --param l1-cache-line-size=64 --param l2-cache-size=512 -mtune=znver2 -dumpbase -
It's likely some bad code assumption that when you have certain intrinsics, some other thing is available. Lots of modern intrinsics work for 32-bit code. Could you try narrow down which of the -m* settings cause the failure for you? That'll help quite a bit. (You've already got the list, but FWIW: https://wiki.gentoo.org/wiki/Gcc-ICE-reporting-guide#Expand_-march.3Dnative.2C_exact_gcc_version_and_other_system-specific_options)
Gonna test the -m* settings.

Only the -mf16c option fails to build. All other -m* options from the gcc -march=native -E | grep cc1 output in comment #1 when combined individually with -march=i686 build without issues.
In all fairness I should move back to using -march=i686 (this is x86 container) but -march=native has revealed some interesting bugs and it seems to be "authentic" enough to a real x86... I don't know.
This bug blocks stabilization of openexr-3.1.5 for x86. How shall we continue to handle this? The issue is tied to specific intrinsics used and the use of -march=native. The gcc (11.3.1) info page lists the problematic F16C intrinsics only for recently enough processors (skylake and later for Intel, bdver2 and later for AMD). Is this an issue with gcc using wrong assumptions while running in a containerized environment? Is this an issue to be reported upstream? So far I don't think so
I wonder if we can get away using flag-o-matic here... like replace-cpu-flags (or replace-flags) if use x86; then; replace-cpu-flags -march=native -march=i686 fi can't say I've ever seen that being done before, but doesn't sound too bad.
Wasn't aware flag-o-matic has these replace-* functions. Sounds like a way to go. I'll test it and see if it works.

This sets the -mf16c intrinsic which isn't available on every x86_32 arch. The patch replaces -march=native with -march=i686 if x86 is used. Also disable a failing test for x86.
