Description:
------------
Hi,
I've got a script which uses all my memory and cpu. I tested with php as CGI and build-in. Both had memory limits on.

The script can be found at http://ward.webware.be/test_func.phps

The problem is the $empty parameter which is passed twice "by reference".

Reproduce code:
---------------
see url.

Expected result:
----------------
PHP had to kill the script after using more then 8mb of ram.

Actual result:
--------------
The script uses all the cpu and memory.

Sorry, but your problem does not imply a bug in PHP itself.  For a
list of more appropriate places to ask for help using PHP, please
visit http://www.php.net/support.php as this bug system is not the
appropriate forum for asking support questions. 

Thank you for your interest in PHP.

There are many ways to accomplish this kind of infinite recursion which eats up the stack.
