If the parent class is not defined, it also end up with segmentation
fault.
<?php
class base {
function __construct(){
call_user_func(array($this,'parent::__construct'));
}

parent::__construct();
}
}

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.
