// Ensure that we don't ICE when an alias that has escaping bound vars is
|
|
// required to be live. This is because the code that allows us to deduce an
|
|
// appropriate outlives bound for a given alias type (in this test, a
|
|
// projection) does not handle aliases with escaping bound vars.

// See <https://github.com/rust-lang/rust/issues/117455>.
