Description
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() {}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
