Internal compiler error unexpected region in outlives inference: ReEmpty when missing Self bound on struct. Reproducible on stable/beta/nightly on playground.

Also, not sure if it already has it's own issue, but rustc is causing an illegal instruction error when you run it with BACKTRACE=1 on this code as well, which is also reproducible on playground if you turn the backtrace setting on.

I tried this code:

pub trait Foo {
    type Type;
}

pub struct Bar<T>(<Self as Foo>::Type)
where
    Self: ;

fn main() {}

(Playground)

I expected to see this happen:

error[E0277]: the trait bound `Bar<T>: Foo` is not satisfied
 --> src/main.rs:5:19
  |
5 | pub struct Bar<T>(<Self as Foo>::Type)
  |                   ^^^^^^^^^^^^^^^^^^^ the trait `Foo` is not implemented for `Bar<T>`

Instead, this happened:

error: internal compiler error: src/librustc_typeck/outlives/utils.rs:172: unexpected region in outlives inference: ReEmpty

thread 'rustc' panicked at 'Box<Any>', src/librustc_errors/lib.rs:912:9

error: internal compiler error: unexpected panic

note: the compiler unexpectedly panicked. this is a bug.

note: we would appreciate a bug report: https://github.com/rust-lang/rust/blob/master/CONTRIBUTING.md#bug-reports

note: rustc 1.40.0-nightly (ddf43867a 2019-09-26) running on x86_64-unknown-linux-gnu

note: compiler flags: -C codegen-units=1 -C debuginfo=2 --crate-type bin

note: some of the compiler flags provided by cargo are hidden
