This is causing an infinite recursion, but works fine on 5.2.15-dev.

Description:
------------
When calling parent::__construct using call_user_func_array, a segfault
occurs. 
Script to reproduce attached below.

This worked in 5.2.14.

Expected: instantiation of class
Actual: segfault

Notes: Only occurs with multiple nesting levels. A single level doesn't
cause 
this.

Test script:
---------------
<?

class baseA{
        function foo(){
                return 'bar';
        }

        function __construct(){
                foo();
        }
}
class baseB extends baseA  {
    function __construct(){
        $args = func_get_args();
        call_user_func_array(array($this, 'parent::__construct'),
$args);
    }

        }


class demo extends baseB{
    function __construct(){
        $args = func_get_args();
        call_user_func_array(array($this, 'parent::__construct'),
$args);
    }
}

$z = new demo('d');
?>

Expected result:
----------------
instantiation of class

Actual result:
--------------
segfault.
