Comment 2 Sven Wegener gentoo-dev 2024-04-28 20:18:24 UTC
I'm able to reproduce and the issue comes from the settings code written in rust not being compiled with lto and the top-level linking then failing. Need to look further into it, as forcing -Clinker-plugin-lto for the rust code causes other build issues.

lto_tinderbox has reproduced this issue with version 5.0.5 - Updating summary.
