Description:
------------
Attempting to validate an XML document against a schema containing a
CDATA section with whitespace preceeding the opening tag causes the PHP
Interpreter to crash with an exception in Windows 2000/XP and 2003 on
both IIS and Apache.

Example:
<?xml version="1.0"?>
<test xmlns="http://www.php.net/bugtests">
	<value>
		<![CDATA[ 
			test 
			]]>
	</value>
 
</test>

Validating the schema using xmllint with libxml 2.6.22 DLL works as
expected and does not crash.


I found a similar, possibly the same bug
(http://bugs.php.net/bug.php?id=37435&edit=2) which has been closed. As
I could not reproduce it with xmllint, I figure that it must be the PHP
interpreter.

Reproduce code:
---------------
crash-test.php:
<?php
    $xml = new DOMDocument('1.0');
    $xml->load('crash-test.xml');

    $xml->schemaValidate('crash-test.xsd'); // crash here
?>

crash-test.xml:
<?xml version="1.0"?>
<test xmlns="http://www.php.net/bugtests">
	<value>
		<![CDATA[ 
			test 
			]]>
	</value>
 
</test>

crash-test.xsd:
<?xml version="1.0" encoding="UTF-8" ?>
<xs:schema
	xmlns:xs="http://www.w3.org/2001/XMLSchema"
	targetNamespace="http://www.php.net/bugtests"
	 xmlns="http://www.php.net/bugtests"
	elementFormDefault="qualified">

	<xs:element name="test">
		<xs:complexType>
			<xs:sequence>	
				<xs:element maxOccurs="unbounded" name="value" type="xs:string"
/>
			</xs:sequence>
		</xs:complexType>
	</xs:element>	
</xs:schema>


Expected result:
----------------
validated schema

Actual result:
--------------
php interpreter crashes with exception
