Please try it with a less aggressive optimization level.
Looks like version 5.101.0 build fine using clang 15.0.7
Created attachment 155399 [details] version 5.101.0 w/ clang 15.0.7 build log
v5.102.0 also built fine
v5.102.0 also built fine then this is fixed, thanks for testing

That's because of a workaround in downstream Qt: https://gitweb.gentoo.org/repo/gentoo.git/commit/?id=92c1834342000220f71cf7e9b9ad0ed111d9e084
At this point, I suspect it's a bug in Clang's implementation of -fstack-clash-protection, given we've seen some odd behaviour with Chromium too. GCC's implementation of stack clash protection works fine. We've stopped enabling it by default for Clang.
