// Regression test for #37291. The problem was that the starting
// environment for a specialization check was not including the
// where-clauses from the impl when attempting to normalize the impl's
// trait-ref, so things like `<C as Foo>::Item` could not resolve,
// since the `C: Foo` trait bound was not included in the environment.
