Can you try to get a backtrace and figure out which exact command dies? 78[1G[K[34m20:38.15(B[m process didn't exit successfully: `/var/notmpfs/portage/www-client/firefox-102.5.0/work/firefox_build/release/build/gecko-profiler-82abe86554f4eece/build-script-build` (signal: 11, SIGSEGV: invalid memory reference)(B[m(B[m
Oh, I bet this is bug 877267, and we may need to then backport the patch.
Producing a backtrace is harder than I thought. The issue is actually random. I see crashes in both clang++ and rustc. But so far I couldn't catch any of them in gdb...
I tried to fix it by installing firefox 107...and it built successfully
(In reply to Maciej A from comment #5) > Producing a backtrace is harder than I thought. > The issue is actually random. I see crashes in both clang++ and rustc. > But so far I couldn't catch any of them in gdb... You can try what I did in bug 877267 (get a core file then invoke gdb) but there's not much need as I think we know the problem.
Reproduced this in an empty container with clang profile, fixed by following the steps from bug 877267.
