Description Frederik Pfautsch 2024-07-25 21:01:00 UTC 
During linking of vmlinux.o, lld.ld crashes with a stacktrace (log attached with last few log lines).

Reproducible: Always

Steps to Reproduce:
1. Build gentoo-sources with a purely clang/llvm-based toolchain



Problem similar to https://github.com/llvm/llvm-project/issues/72026. PR https://github.com/llvm/llvm-project/pull/85081 fixes this issue and the kernel builds/links successfully.

Yeah, the patches are proving difficult to backport cleanly without introducing test failures. mgorny spent the last few days trying.

uff, that was fast. Alright, sorry for the duplicate, I looked for something like this but must have missed it. Thanks for working on it! (I noticed the test case issue and just disregarded them to test if the patch works in general)
