If dev-lang/rust-1.79.0 is compiled with "wasm", it fails with the error: failed to run custom build command for `compiler_builtins v0.1.109` (The command itself is a bit long, so look for yourself in the attached build.log)
You have failed to attach the build log. Please also provide emerge --info.

(In reply to Mike Gilbert from comment #1) > You have failed to attach the build log. Please also provide emerge --info. Yeah, sorry about that. I guess I am either stupid or it didn't upload because it was larger than the upload limit.
