@gurry

This seeeems to bisect to #122078 🤔 cc @gurry

@matthiaskrgr

Thanks @matthiaskrgr. Will take a look.

@rustbot claim

Reduced further:

trait Trait<const N: Trait = bar> {
    fn fnc(&self) {
    }
}

@gurry

@gurry the original (none reduced) one still ices 😅

@matthiaskrgr

From what I can tell, it seems to have been fixed @matthiaskrgr : https://play.rust-lang.org/?version=nightly&mode=debug&edition=2021&gist=08acb20454a44db397241bb6aeab04c9

Looks like I'm missing something 😟

I have now opened PR #122927 to test the below original reproducer:

trait Trait<const N: Trait = bar> {
    fn fnc<const N: Trait = u32>(&self) -> Trait {
        bar
    }
}

fn main() {}

@matthiaskrgr

Sorry @matthiaskrgr for causing the issue to be closed via the PR merge without asking you first. If you still believe the ICE is not fixed please reopen it.
