Description:
------------
If I run php in interactive mode (-a option), and use the code I supplied below, php crashes with segmentation fault.

It works well without interactive mode.

Reproduce code:
---------------
<?PHP
 $vars['one'] = '1' ;
 $vars['two'] = '2' ;

 foreach ($vars as $key => $value)
 { print "$key => $value\n" ; }

?>


Expected result:
----------------
The following output:
one => 1
two => 2


Actual result:
--------------
[user@host ~]$ php -a
Interactive mode enabled

<?PHP
 $vars['one'] = '1' ;
 $vars['two'] = '2' ;

 foreach ($vars as $key => $value)
 { print "$key => $value\n" ; }

one => 1
Segmentation fault
