after much testing (based on gentoo/stage3:amd64-desktop-systemd docker image), I found the following: dev-lang/rust-bin-1.69.0-r1: compiles fine dev-lang/rust-bin-1.71.0: compiles fine dev-lang/rust-bin-1.72.0: compiles fine dev-lang/rust-bin-1.73.0: compiles fine dev-lang/rust-1.71.1 + sys-devel/llvm:16: doesn't compile dev-lang/rust-1.73.0 + sys-devel/llvm:17: compiles fine dev-lang/rust-1.74.1 + sys-devel/llvm:17: compiles fine I conclude that this error is probable something about sys-devel/llvm:16 and/or dev-lang/rust-1.71.1 Workaround would be to either use dev-lang/rust-bin or use unstable sys-devel/llvm + dev-lang/rust This bug should therefor "fix itself" as soon as sys-devel/llvm:17 and >=dev-lang/rust-1.73.0 is marked stable Thanks to @pastalian on #gentoo-proxy-maint for pointing me towards llvm
