PHP version:      5.3.6
Package:          Scripting Engine problem
Bug Type:         Bug
Bug description:Multiple closure invocations 'using' a static variable crashes engine

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.
