// run-pass
#![allow(unused_variables)]
// This code was creating an ICE in the MIR type checker. The reason
// is that we are reifying a reference to a function (`foo::<'x>`),
// which involves extracting its signature, but we were not
// normalizing the signature afterwards. As a result, we sometimes got
// errors around the `<u32 as Foo<'x>>::Value`, which can be
// normalized to `f64`.
#![allow(dead_code)]
trait Foo<'x> {
type Value;
}
impl<'x> Foo<'x> for u32 {
type Value = f64;
}
struct Providers<'x> {
foo: for<'y> fn(x: &'x u32, y: &'y u32) -> <u32 as Foo<'x>>::Value,
