dmesg also reports: [Mon Jul 22 09:32:42 2024] traps: freestanding[7757] general protection fault ip:6080d5fc05ce sp:7ffdd1e55078 error:0 in freestanding[6080d5fa1000+22000]
Two different issues here: - enabling >=O2 crashes with a misaligned stack on function entry, see the upstream bug. Thanks Arsen for finding this! - building the tests with clang fails on Gentoo because we enable the stack protector in /etc/clang/gentoo-hardened.cfg, so maybe for that we can do tc-is-clang && append-flags -fno-stack-protector in the ebuild.
