//@ compile-flags: -Znext-solver

// When checking that the impl method where-bounds are implied by the trait,
// we prove `<() as A<T>>::Assoc: A<T>` in the environment `<() as A<T>>::Assoc: A<T>`.
//
// Normalizing `<() as A<T>>::Assoc` is ambiguous in that environment. The
// where-bound `<() as A<T>>::Assoc: A<T>` may apply, resulting in overflow.
