Created attachment 856252 [details]
build.log.xz

build log and emerge --info (compressed because it exceeds attachment limit, use 'xzless' to read it)

I can see it (and several others) also but at the end MariaDB can be compiled and installed. Seems more a "minor" QA issue that has to fixed upstream than a real blocker.

They're not minor - see https://wiki.gentoo.org/wiki/Project:Toolchain/Modern_C_porting. They can result in miscompilations with compilers that reject them entirely (as it'll change the result), like Clang 16, and GCC 14 (not 13).
