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.

Actual result:
--------------
(gdb) run -a
