Description:
------------
PHP crash by using the DOM function getElementById() (PHP kill the Apache server process on Windows, with Apache v1.3.27 and v2.0.48).

Reproduce code:
---------------
<?php
$dom = new DomDocument;
$dom -> load('essai.xml');

if ($dom -> validate()) {
	$menu = new DomDocument;
	$menu = $dom -> getElementById('a');
	echo $menu -> firstChild -> data;
}
?>

essai.xml :
-----------

<?xml version="1.0"?>
<!DOCTYPE essai [
	<!ELEMENT essai (truc+)>

	<!ELEMENT truc (#PCDATA)>
	<!ATTLIST truc
		id	ID		#REQUIRED>
]>

<essai>
	<truc id="a">1</truc>
</essai>

Expected result:
----------------
1

Actual result:
--------------
Nothing, PHP and the server crash...
There is the same result with an external doctype.
When I call getElementById(id) with an id who doesn't exist in the XML file, there is no crash.

It only crashes, if you use validate(). Without it seems to work.

I'm looking into it.
