ICE: mir_const_qualif: `index out of bounds: the len is 0 but the index is 0`

[matthiaskrgr]

Similar to #125670 but different query stack

auto-reduced (treereduce-rust):

use std::fmt::Debug;

trait Foo<Item> {}

impl<Item, D: Debug + Clone> Foo for D {
    fn foo<'a>(&'a self) -> impl Debug {
        const { return }
    }
}

original:

#![doc(hidden)]

use std::fmt::Debug;


trait Foo<Item> {
    fn foo<'a>(&'a self) -> impl Debug where : 'a;
}

impl<Item, D: Debug + Clone> Foo<Output = usize> for D {
    fn foo<'a>(&'a self) -> impl Debug where Item: 'a {
    const { return }
}
}
