Created attachment 869749 [details] Build log for dev-libs/jansson-2.14-r1 It compiles fine with GCC, GCC LTO, and LLVM w/o LTO. I also made sure the LDFLAGS matched each time. emerge --info: Portage 3.0.49 (python 3.11.5-final-0, default/linux/amd64/17.1/clang, gcc-12, glibc-2.37-r3, 6.1.46-gentoo-dist-hardened x86_64)

!!! Please attach the following file when seeking support: !!! /var/tmp/portage/dev-libs/jansson-2.14-r1/work/jansson-2.14/config.log Albeit even without that I can guess what happened. It does tc-ld-force-bfd (I forget why, or if still needed -- think it was some version script junk), and then there's probably errors because it tried to use ThinLTO with bfd. Ideally ebuild "should" strip-unsupported-flags to sort this out, but it wouldn't work right now. Had talked about this a bit back in: https://github.com/gentoo/gentoo/pull/28355#discussion_r1032998656 tl;dr not much you can do right now but just not do lto with clang for this package.

Sounds good! Apologies for not attaching the file, I'll remember that for next time.
