Description:
------------
This little script creates a segfault on every version of php i came
across (4.3.2, 4.3.3rc1, 5.0.0b2). When you replace 0 with "0", it
works.
Reproduce code:
---------------
<?php
$obj->foo = "bar"; // or anything else that creates an object
print $obj->{0};
?>
Expected result:
----------------
Notice: undefined property: 0... or something alike
Actual result:
--------------
