// Here, there are two types with the same name. One of these has a `derive` annotation, but in the
// expansion these `impl`s are associated to the *other* type. There is a suggestion to remove
// unneeded type parameters, but because we're now point at a type with no type parameters, the
// suggestion would suggest removing code from an empty span, which would ICE in nightly.
