Description:
------------
When a closure is invoked more than once that 'uses' a variable defined with the 
'static' keyword, the scripting engine crashes. No output is sent to the browser 
and server issues no response.

If we remove the 'static' keyword from the variable declaration, the issue is 
resolved. Note that in PHP 5.3.5, this issue was not present.

Test script:
---------------
ftp://guest:guest@bytes1.dyndns.org/PUBLIC/php_bug/php_bug.php

Expected result:
----------------
1<br>2<br>3<br>


Actual result:
--------------
No result. Scripting engine crashes.
