compiler crash - when using 'self lifetime

[danoctavian]

Minimal example of code that crashes rustc:

extern mod std;
use std::iterator;

pub fn get_mode<T : Iterator<&'self int>>(it : & T) {}
fn main() {}

Error:
rust: task failed at 'explicit failure', rust-0.7/src/librustc/rustc.rs:354

Closing as a dupe of #6396.
