Description:
------------
If you reference an array (with instances) and 'use' that array in a closure (without referencing it again) you get a segmentation fault

Using 'use (&$ar)' iso 'use ($ar)' fixes it. 

Test script:
---------------
http://www.correct.nl/bug_closure_b338f79f99c96c55fc879211ca2fe370.php.txt

Expected result:
----------------
exit 0, I guess

Actual result:
--------------
