Endless Loop of Error Messages when parsing in Beta and Nightly Compiler

[CryZe]

I just encountered an infinite loop of error messages when compiling this simple code:

pub fn do_stuff() {
    a -= 
}

PlayPen Link (Warning: will most likely crash your browser)

The error messages I get are:

src\lib.rs:3:1: 3:2 error: unexpected token: `<eof>`
src\lib.rs:3 }
             ^
src\lib.rs:3:1: 3:2 error: unexpected token: `<eof>`
src\lib.rs:3 }
             ^
src\lib.rs:3:1: 3:2 error: unexpected token: `<eof>`
src\lib.rs:3 }
             ^
src\lib.rs:3:1: 3:2 error: unexpected token: `<eof>`
src\lib.rs:3 }
             ^
