Which rustc version is this? I've been getting stuff like this lately too, so I've completely disabled the asmjs builds for my crate.

The error is on num-integer, not num-traits, but anyway it should not be possible for any crate code to cause a compiler crash. Please file a bug on rust-lang/rust itself!

Sorry for mistakenly creating the issue on this crate. This crate compiles fine.

@cuviper But it only happens for the num-integer crate so I opened the issue on https://github.com/rust-num/num-integer/issues/28 because I'm not sure how and why I'd report this to rust-lang/rust.
