Found this in when debugging #92626.

Code

struct Test<T>([T; 1]);

impl<T> std::ops::Deref for Test<T> {
    type Target = [T; 1];
    
    fn deref(&self) -> &[T; 1] {
        &self.0
    }
}

fn test() {
    let mut out = Test(todo!());
    let blah = out.len();
}

error: internal compiler error: unexpected panic

note: the compiler unexpectedly panicked. this is a bug.

Since I'm already pretty far with a solution to #92626, I'll claim this too. :-)

@rustbot claim

edit: Found a solution, will put up a PR in the morning.

@compiler-errors compiler-errors changed the title ICE during method lookup/confirmation (due to autoderef, with impl Deref<Target = [T; 1]> for MyType) Calling slice method on newtype wrapper that implements Deref<Target=[_; 1]> causes ICE Jan 7, 2022
