ICE static call to invalid vtable

[ghost]

I was trying to compile the following code:

#![feature(core)]
#![feature(unboxed_closures)]
enum Thunk<A, F: Fn<A>> { Unevaluated(F, A), Evaluated(F::Output), }
impl <A, F: Fn<A>> Thunk<A, F> {
    fn eval(self) -> (Self, F::Output) where F::Output: Copy {
        match self {
            Thunk::Unevaluated(f, a) => {
                let r = Fn::call(&f, a);
                (Thunk::Evaluated(r), r)
            }
            Thunk::Evaluated(r) => (self, r),
        }
    }
}
fn main() {
    let (_, v) = Thunk::Unevaluated(|x: i32| { x + 1 }, (3,)).eval();
    println!("{}" , v);
}

And got the following compiler error:

error: internal compiler error: static call to invalid vtable: VtableClosure(DefId { krate: 0, node: 97 },Substs[types=[[];[];[]], regions=eras
ed])
note: the compiler unexpectedly panicked. this is a bug.

[tamird]

Still ICEs.

[arielb1]

Minimal:

#![feature(core)]
#![feature(unboxed_closures)]

fn main() {
    let k = |x: i32| { x + 1 };
    Fn::call(&k, (0,));
}

Triage: tracked by glacier

[Mark-Simulacrum]

No longer ICEs today. E-needstest. I'm somewhat concerned though because this is the second glacier-tracked ICE that I've seen "fixed."

[arielb1]

This was only broken because of the old meth code.
