Please include the tarball the GCC ebuild makes on failure, and emerge --info. If you're willing, please try to follow https://wiki.gentoo.org/wiki/Gcc-ICE-reporting-guide. First, try run the failing command manually, then try get preprocessed source and share it here.
Created attachment 892771 [details] emerge --info
No tarball?
Nope not yet, I accidently removed the /var/tmp/portage/ files. sys-devel/gcc-14.1.1_p20240511-r1 compiles without the error.
Compiling gcc:13 with gcc:14 selected succeeds therefore the error is not reproducable and/or a sporadic concurrent race condition.
