ICE when using RTN in the where clause of a trait

[tmandry]

Code

#![feature(return_type_notation)]

trait LocalService {
    type Request;
    type Response;
    async fn call(&self, req: Self::Request) -> Self::Response;
}

trait Service: LocalService
where
    Self: Send,
    Self::call(..): Send,
{}

Note that rewriting the RTN to be an associated type bound like trait Service: LocalService<call(..): Send> fixes the ICE.

This is fixed by #132047

[matthiaskrgr]

bisects to #129629
