ICE: debuginfo::set_members_of_composite_type()

[metajack]

Compiling this modified glfw-rs with -Z extra-debug-info:
https://github.com/metajack/glfw-rs/tree/servo-rustup

gives:
``error: internal compiler error: debuginfo::set_members_of_composite_type() - Already completed forward declaration re-encountered.`

This is caused by

pub struct Window<'a> {
    callbacks: WindowCallbacks<'a>
}
struct WindowCallbacks<'a> {
    pos_callback:                Option<WindowPosCallback<'a>>,
}
pub type WindowPosCallback<'a> = 'a |&Window, i32, i32|;

@jdm Thanks for finding the code in question, it works great as a minimal test case!
