how it was called + build.log

[Comment 3 Sam James 2024-09-21 07:53:13 UTC]

I started seeing this recently too (last few days) but not investigated it yet.

It might be caused by new LLVM (llvm-readelf).

bunch of files in a lzip tarball with 1 test failed.

inside of the lzip tarball:
how_it_was_called.txt emerge_--info.txt /var/tmp/portage/sys-devel/mold-2.32.1/{build-info/,files/,temp/,work/**{.log}} /var/lib/portage/ /etc/portage/ /var/log/portage/elog/sys-devel/mold-2.32.1:20240921-040746.log

[Comment 5 Arniii 2024-09-21 08:04:14 UTC]

reproducible with sys-devel/mold-2.33.0-r1

[Comment 6 Sam James 2024-09-21 08:11:24 UTC]

right, I think something external to mold changed.
