line!() macro is confused by closures.

On
rustc 1.2.0-nightly (8937ec1 2015-06-15)

Linux 3.13.0-46-generic #79-Ubuntu SMP x86_64 GNU/Linux

This program:

fn main() {
    let func = move || {
        println!("ALIVE {}:{}", file!(), line!());
        println!("ALIVE {}:{}", file!(), line!());
        println!("ALIVE {}:{}", file!(), line!());
        println!("ALIVE {}:{}", file!(), line!());
        println!("ALIVE {}:{}", file!(), line!());
        println!("ALIVE {}:{}", file!(), line!());
        println!("ALIVE {}:{}", file!(), line!());
    };

    func();
}

prints a bunch of time:
ALIVE /tmp/blub.rs:2

Confusingly enough it works correctly on the playground.

Regression happened somewhere between stable (1.0) and current beta (1.1).
