//! This test used to ICE: #121134
//! The issue is that we're trying to prove a projection, but there's
//! no bound for the projection's trait, and the projection has the wrong
//! kind of generic parameter (lifetime vs type).
//! When actually calling the function with those broken bounds, trying to
//! instantiate the bounds with inference vars would ICE.
