Emacs crashes when adding curly brackets to function

[Christoph-Simon Senjak]

I generate a file with

emacs a.php

Then I type in

function bla ()

in the first line, and then add the curly bracket, emacs uses 100% cpu. The same does not happen when the function is not in the first line of the file.
