Description Herb Miller Jr. 2021-08-18 17:11:06 UTC 
Not sure if it's actually a Qt w/LTO problem, but build log shows lto-specific build error.

Reproducible: Always

I messed up posting the build log initially.

Probably the same as https://bugs.gentoo.org/807598#c7 : libQt5UiTools.a was built by an older compiler. As a workaround you can try rebuilding /usr/lib64/libQt5UiTools.a:

    # emerge -v1 /usr/lib64/libQt5UiTools.a
