Summary

The compiler panics when compiling limn_layout (https://github.com/christolliday/limn) because a dependency (wayland_kbd v0.9.1) panics:

/checkout/src/librustc/ich/impls_ty.rs:78: TypeIdHasher: unexpected region ReLateBound(DebruijnIndex { depth: 1 }, "BrEnv")

NOTE: This does not occur when CARGO_INCREMENTAL=0.

rustc version:

rustc 1.22.0-nightly (a47c9f870 2017-10-11)
binary: rustc
commit-hash: a47c9f870f13603a06ffe63ab4834fc716912843
commit-date: 2017-10-11
host: x86_64-unknown-linux-gnu
release: 1.22.0-nightly
LLVM version: 4.0

Full backtrace:

I get this issue with compiling the calculate crate. nightly-2017-10-09 works though.
