ignore implied bounds with placeholders given the following code: ```rust trait Trait { type Ty<'a> where Self: 'a; } impl<T> Trait for T { type Ty<'a> = () where Self: 'a; } struct Foo<T: Trait>(T) where for<'x> T::Ty<'x>: Sized; ``` when computing the implied bounds from `Foo<X>` we incorrectly get the bound `X: !x` from the normalization of ` for<'x> <X as Trait>::Ty::<'x>: Sized`. This is a a known bug! we shouldn't use the constraints that arise from normalization as implied bounds. See #109628. Ignore these bounds for now. This should prevent later ICEs. Fixes #112250 Fixes #107409 |
