Description:
------------
Just call php with -a option to enter in interactive mode. Then open
php tags <? (short or long: <?php), write 'foreach' loop and php dies.
The list of modules is long:

Reproduce code:
---------------
homero:/home/luca# /usr/local/stow/php/bin/php -a
Interactive mode enabled
<? foreach(range(1,2) as $i);
Segmentation Fault
homero:/home/luca# /usr/local/stow/php/bin/php -a
Interactive mode enabled
<?
$a = array(1,2,3,4);
foreach ($a as $i);
Segmentation Fault
Expected result:
----------------
The foreach loop.
