Description:
------------
I get a segfault with this script:



Reproduce code:
---------------
<?php
class test {
    public function start() {
        foreach ( $this->array as $foo ) {
            $foo->any_method();
        }
    }
}
$test = new test();
$test->start();
?>

Expected result:
----------------
If $this->array is an array with objects, the method any_method() should be called on $foo. (works well)

If $this->array is an array with strings, int, ..., php should display an error. (works well) (Fatal error: Call to a member function any_method() on a non-object in /var/www/legendz/web/test/test.php5 on line 5 )

If $this->array is an empty array, nothing should happen. (but php crashes)

Actual result:
--------------
