Code

Found originally via https://discord.com/channels/273534239310479360/273541522815713281/1014981030022750328

I managed to reduce it to

fn ice() -> impl AsRef<Fn(&())> {
    todo!()
}

playground link

This seems to be related to a combination of RPIT, missing dyn keyword, implicit HRTB (&()) and parenthesis syntax for the inner trait

Meta

ICEs on both current beta (1.64) and latest nightly (1.65), but not on stable (1.63)

I tried to get my hands dirty and used cargo-bisect-rustc on this and it seems that the regression appeared on nightly-2022-08-06 with cdfd675

Not sure if that helps. I don't think I can diagnose things much further 😅
