struct Thing; pub trait Every { type Assoc; } impl<T: ?Sized> Every for Thing { type Assoc = T; } static I: <Thing as Every>::Assoc = 3;
I investigated using the above code. The ICE occurs when we call the layout query during the inhabitedness check for the static I. Given the assignment to 3 in the declaration static I: <Thing as Every>::Assoc = 3 its type should normalize and resolve to i32 or something, but because we have a T: ?Size constraint in the impl that is not possible. So we get back a tykind Infer instead. When that Infer type is passed to layout_of_uncached it ICEs.
That explains why removing the ?Sized constraint makes the issue go away.
