CARGO_INCREMENTAL=1 crashes `wayland_kbd` @ impls_ty.rs:78 - unexpected region

[fschutt]

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

[mmstick]

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

[daboross]

I have this issue compiling my own crate (http://github.com/daboross/screeps-rs) on nightly-2017-10-11.

Duplicate of #45161, should be fixed in current nightly or at latest in the next nightly.

Closing as duplicate of #45161.
