Created attachment 546562 [details] Build log This package has become a dependency of www-client/firefox but it fails during its ebuild, thus blocking an upgrade for firefox. The specific error message is: RuntimeError: failed to run: /var/tmp/portage/dev-lang/rust-1.25.0/work/rust-stage0/bin/cargo build --manifest-path /var/tmp/portage/dev-lang/rust-1.25.0/work/rustc-1.25.0-src/src/bootstrap/Cargo.toml --verbose --verbose --locked --frozen Log from the ebuild is attached. Output of emerge --info will follow shortly.

Can you try with rust-1.28.0-r1? You might need the workaround from https://bugs.gentoo.org/663690#c27.
I tried with 1.28.0-r1 but it crashed the same way. Note that I had to change a use flag to -cargo.
This problem persists with 1.29.1, wth the same binary of cargo causing the crash. How was this binary built? If it was built on an AMD64 system using -m32 then it is likely that it could use SSE2 instructions; the only IA32 processor these instructions can run on is the Pentium 4. Since I am using an AMD Athlon MP system this would cause a trap 1. [Likewise on Pentium III, Pentium II, AMD K6 and earlier.] Is it possible to build this binary using -march=i486? That will produce object code that will run on any IA32 processor currently supported by Linux.
Ohh, that could make sense. I've filed an upstream bug.
Okay, so, I think this makes sense. In terms of the Rust ebuilds currently, Gentoo's x86 arch translates to i686. For i586 and older, upstream does not provide rustc and cargo binaries, and so you'd have to cross-compile.
