Try installing sys-libs/compiler-rt-sanitizers (use=profile must be enabled) and re-emerging. I've seen this error a few times and they tend to work with this. Probably worth adding as a dependency if clang/lld is being used and use=pgo

Yes, that did the trick. Many thanks for the hint!

I had sys-devel/clang-runtime built with USE="-sanitize" for whatever reason I forgot and as a consequence sys-libs/compiler-rt-sanitizers had not been built at all.

So I second it could be a good idea to add compiler-rt-sanitizers as dep for +pgo builds for clang-based systems.

How could the ebuild check that? It can't really without us just adding it to @system on such profiles (which might be ok).
