Bug description:  PHP5.1 overloading, Cannot access private property 

Description:
------------
chaining of objects using __get() works like a charm, however if using
chaining and using __set() at the end of the chain to set a property, php
fails reporting: "Fatal error: Cannot access private property A::$p in
<file> on line <line>"

please keep in mind that i'm using php5.1 (RC1), chaining should work in
this version, doesn't it?

posted reproduce code from
http://www.sitepoint.com/forums/showthread.php?p=2230679#post2230679


Reproduce code:
---------------
class A {
	private $p;
	function __get($name){
		return $this->$name;
	}
	function __set($name, $value) {
		$this->$name = $value;
	}
}
class B {
	private $t;
	function __get($name){
		return $this->$name;
	}
	function __set($name, $value) {
		$this->$name = $value;
	}
}
$a = new A;
$b = new B;
$a->p = $b;
$b->t = "foo";

echo $a->p->t;
$a->p->t = "bar";
echo $a->p->t;

Expected result:
----------------
foobar

Actual result:
--------------
foo
Fatal error: Cannot access private property A::$p in...
