Operating system: Windows XP SP3

PHP Bug Type:     Reproducible crash
Bug description:  call_user_func_array fails to call parent from inheriting class

Description:
------------
When class C extends B, which extends A, calls from B to its parent 
methods fail when using call_user_func_array(). Using parent::func()
works just fine.

Reproduce code:
---------------
class A {
  function func( $str ) {
    echo $str;
  }
}

class B extends A {
  public function func( $str ) {
    call_user_func_array( array( $this, 'parent::func' ), array( $str )
);
  }
}

class C extends B {
  public function func( $str ) {
    parent::func( $str );
  }
}

$c = new C;
$c->func( 'This should work!' );

Expected result:
----------------
The code should output "This should work!".

Actual result:
--------------
PHP crashes with backtrace (yes, only one line):
