Description:
------------
PHP5 crashes with the attached code.
It seems to crash at the Entry 'GLOBAL' and some others.

Reproduce code:
---------------
This code is in a function. It should global every variable:
foreach($GLOBALS as $field=>$value) if($field!='t' && $field!='r' && $field!='field' && $field!='value') global ${$field};

The following code works, but is TOO SLOW!
foreach($GLOBALS as $field=>$value) if($field!='t' && $field!='r' && $field!='field' && $field!='value') eval('global $'.$field.';'); // Use eval for PHP5 compatibility!

Expected result:
----------------
Every variable should be globales - only $t, $r, $field and $value not.

Actual result:
--------------
No output from PHP. It crashes and gives nothing back to Apache.
