Code

playground

struct S;

impl S {
    fn foo(_: Box<Option<S>>) {}
    fn bar() {
        Self::foo(None)
    }
}

On stable the code produces the following error as expected:

Interesting, this is rustc now, right?
There has been as similar rustdoc ice: #79465

Yes, this can be hit with rustc .\src\lib.rs --crate-type lib --edition 2021 or cargo c for example.
I tried running the code in #79465, but it seems to have been fixed by now.
