ICE: Can't reflect unsized type

[dotdash]

Code:

extern crate debug;

trait Bar {
    fn bar(&self);
}

struct A {
    _x: int,
}

struct Outer<Sized? T> {
    pub v: T
}

impl Bar for A {
    fn bar(&self) {}
}

fn main() {
    let a = A { _x: -5 };

    let o1: &Outer<Bar> = &Outer { v: a };
    println!("{:?}", &o1);
}

Output:

rustc 0.12.0-pre (5550edef4 2014-08-27 06:01:18 +0000)
