Issue: rustc panicked while refactoring crossbeam_channel
Labels: I-ICE,T-compiler,A-incr-comp,C-bug

I'm refactoring some crossbeam_channel messages and I get a rustc panicked error if I run `cargo test`.
`cargo build` does not complain and `cargo clean` _fixes_ the error.

I have no idea how to reproduce it and it only happens from time to time. So I've added the backtraces with =1 and =full.

I hope that helps
