Description:
------------
I am running php5rc2 and apache 2.0.49 on winXP sp1. php4 compatability is enabled.

When running the following piece of code i got Application error from apache.exe. the error text is "The instruction at "0x0068d6ff" referenced memory at 0xffffffff. The memory could not be "read"."

The line causeing the error is:
$this->documentElement->appendChild($element);

Reproduce code:
---------------
class Authors extends DomDocument {
function __construct() {
        //has to be called!
        parent::__construct();
}
    
function addAuthor($name,$password,$group) {
$item = $this->createElement('author');
$attr = $item->setAttribute('name',$name);
$attr = $item->setAttribute('password',md5($password));
if($group=='none'){
$this->documentElement->appendChild($item);
}else{
foreach($this->documentElement->childNodes as $element){
if($element->nodeName == 'group' &&
$element->getAttribute('name') == $group){
$element->appendChild($item);
$this->documentElement->appendChild($element);
}
}
}
}
}

Expected result:
----------------
Unknown
The line:
$element->appendChild($item);
wasnt appending the child so i was testing some quick hacks to see what would work. 

Actual result:
--------------
PHP crash and no output.
