Labelled break outside of for loop doesn't work

[hoelzro]

(using Rust compiled from commit dc4560d)

The following code fails to compile:

fn main() {
    'outer: loop {
        match () {
            () => {
                for std::uint::iterate(0, 8) |_| {
                    loop {
                        break 'outer;
                    }
                }
            },
        }
    }
}

with the following error:

/tmp/test.rs:7:24: 7:37 error: internal compiler error: Break to unknown label   
/tmp/test.rs:7                         break 'outer;
                                             ^~~~~~~~~~~~~

If you comment out the for loop, it compiles fine.

This is a known bug - #4131 . I'm closing this as a duplicate, but keep the bug reports coming! It's always better to have a duplicate than to miss out on hearing about an unreported bug.
