Description:
------------
I used the Xinclude PHP5 example from Bitflux. Then when I tried to iterate through the resulting DOM object I got an access violation.

Reproduce code:
---------------
<?
class VariableStream {
    var $position;
    var $varname;
    function stream_open($path, $mode, $options, &$opened_path) {
        $url = parse_url($path);
        $this->varname = $url["host"];
        $this->position = 0;
        return true;
    }
    function stream_read($count) {
        $ret = substr($GLOBALS[$this->varname], $this->position, $count);
        $this->position += strlen($ret);
        return $ret;
    }
    function stream_eof() {
        return $this->position >= strlen($GLOBALS[$this->varname]);
    }
    function url_stat() {
        return array();
    }
}

$xmlstring = '<?xml version="1.0"?>
<foo xmlns:xi="http://www.w3.org/2001/XInclude">
    <xi:include href="var://bar#xpointer(/foo/bar)"/>
</foo>';

stream_wrapper_register("var", "VariableStream");

$bar = '<foo><bar>hello world</bar></foo>';
$dom = new domdocument;
$dom->loadXML($xmlstring);
$dom->xinclude();

print nl2br(htmlspecialchars($dom->saveXML()));

foreach ($dom->documentElement->childNodes AS $node) {
	echo '<br>';
	echo $node->nodeName;
	echo ' - ';
	echo $node->nodeValue;
}
?>

Expected result:
----------------
<?xml version="1.0"?>
<foo xmlns:xi="http://www.w3.org/2001/XInclude">
<xi:include href="var://bar#xpointer(/foo/bar)"/>
</foo>

#text - 
bar - hello world
#text - 

Actual result:
--------------
<?xml version="1.0"?>
<foo xmlns:xi="http://www.w3.org/2001/XInclude">
<bar xml:base="var://bar">hello world</bar>
</foo>

#text -
