This bug appeared when I installed php4.0.2, I had 
php4.0.1RC before.

I'm trying to add a reference to Parent to each Child as its created. It seems like the Parent->baseObj property cannot be a reference to $this, its instance.

An example of the code that caused the problem:

class Parent { 
	function Parent(){ 
	$this->baseObj = &$this; 
	function insert($name){ 
		/* This will work 
		if(get_class($this) == 'parent'){
			$this->test[$name] = new Child(); 				$this->test[$name]->baseObj = &$this; 
		else {
			$this->baseObj->test[$name] = new Child(); 
			$this->baseObj->test[$name]->baseObj = &$this->baseObj; 
		/* This will not - says error: call to member function on non-object */ 
		$this->baseObj->test[$name] = new Child(); 			$this->baseObj->test[$name]->baseObj = &$this->baseObj; 

class Child extends Parent{ 
	function Child(){ 
		$this->whatever = 'sometext'; 
	function showMe(){ 
		echo "I exist"; 

$obj = new Parent();
