ice: `calling const FnDef errored when it shouldn't`

[matthiaskrgr]

auto-reduced (treereduce-rust):

const fn f() -> usize {
    5
}

fn main() {
    let _ = [0; FnMut::call_mut(&mut f, ())];
}

original:

// run-pass
#![allow(dead_code)]
const fn f() -> usize {
    5
}
struct A {
    field: usize,
}
fn main() {
    let _ = [0; FnMut::call_mut(&mut f, ())];
}

Is the following code due to the same reason?

const fn a() -> usize {
    b()
}
const fn b() -> usize {
    a()
}
const ARR: [i32; a.call(())] = [5; 6];
fn main() {}
