Another(?) 'failed to get layout for...' ICE

[cehteh]

Code

Minimal Example:

https://play.rust-lang.org/?version=stable&mode=debug&edition=2021&gist=d93a36587d78f6351cf687e2a8f00ace

use core::iter::Peekable;

type FooFn = &'static fn(&Peekable<&dyn Iterator<Item = i32>>);

pub const fn foofail(foofn: FooFn) {
    let _go_boom_ = foofn;
}

[compiler-errors]

This became a post-mono error (so it just has a really bad span) in #111580, but no longer ICEs
