I am not quite sure if the subject covers this. While digging deeper it seems to be in ar. Which then goes for LLVM...? (gdb) bt #0 0x00007ffff651468b in ??

It works for me. Please recompile and *attach* the logfiles and paste the emerge info as described on https://wiki.gentoo.org/wiki/Attach_the_logs_to_the_bug_ticket We need to have all information at hand before ticket assignment, so that the maintainer can look after it in one session with minimal number of callbacks. Please reopen this ticket (Status:unconfirmed) afterwards.
Works for you after LLVM-10?
before LLVM-10. Still no logfiles. Reopen, when attached.
After getting in touch on IRC. I have recompiled llvm-10 and clang-10 without lto. This did not overwrite "ar". Afterwhich glibc compiled without issues.
