<?php
class ObjectShell {
	var $_target;
	
	function ObjectShell(&$target) {
		$this->_target=$target;
		overload('ObjectShell');
	}

	function __get($name, &$value) {
		return true;	
	}

	function __set($name, $value) {
		return true;
	}
	
	function __call($func, $args, &$return) {
		$return=1;
		return true;
	}

	function func1(){
		echo "func1() called ";
		return $this->_target->func1();
	}
}

class Test {
	function func1() {
		return 2;
	}
}

$t=new Test;
$p=new ObjectShell($t);
//this will work
echo $p->func1();
echo "<br>\n";

//this will result "stack overflow" on php4.3.10
//if remove ObjectShell::__set, 
//or ObjectShell::__func1()
//or replace ObjectShell::func1() 
//with func1($a, $b){ return 1 } 
//it will also ok

echo $p->func1(9,7);
echo "<br>\n";
echo $p->var1;
