Bug Type: DOM XML related

PHP Version: 5.1.2
New Comment:
I double checked documentation, node corruption is not mentioned
there.
if the return value of removeChild is assigned to a variable,
everything works as expected:
-----------------8<---------------
$dom = DOMDocument::loadXML('<root><child/></root>');
$xpath = new DOMXpath($dom);
$node = $xpath->query('//child')->item(0);
echo $node->nodeName . "\n";
$res = $GLOBALS['dom']->removeChild($GLOBALS['dom']->firstChild);
echo "nodeType: " . $node->nodeType . "\n";
echo "nodeName: " .$node->nodeName . "\n";
echo "parentNode: " .$node->parentNode . "\n";
---------------->8--------------------
if the return value is ignored:
----------------------------8<---------------
$dom = DOMDocument::loadXML('<root><child/></root>');
$xpath = new DOMXpath($dom);
$node = $xpath->query('//child')->item(0);
echo $node->nodeName . "\n";
$GLOBALS['dom']->removeChild($GLOBALS['dom']->firstChild);
echo "nodeType: " . $node->nodeType . "\n";
echo "nodeName: " .$node->nodeName . "\n";
echo "parentNode: " .$node->parentNode . "\n";
-------------------------->8------------
or goes out of scope:
--------------------8<-----------
$dom = DOMDocument::loadXML('<root><child/></root>');
$xpath = new DOMXpath($dom);
$node = $xpath->query('/root/child')->item(0);
echo $node->nodeName;
function test()
{
$x = $GLOBALS['dom']->removeChild($GLOBALS['dom']->firstChild);
}
test();
echo $node->nodeName;
-------------------->8-----------
$node gets corrupted.

Description:
------------
Using DOMDocument::removeChild corrupts node in the document in some
cases.
Given a node $node and removing a parent node of this node renders
$node unusable (properties are gone, but $node is still of class
DOMElement).
Reproduce code:
---------------
<?php
// This works as expected
$dom = DOMDocument::loadXML('<root><child/></root>');
$xpath = new DOMXpath($dom);
$node = $xpath->query('/root')->item(0);
echo $node->nodeName . "\n";
$dom->removeChild($GLOBALS['dom']->firstChild);
echo "nodeType: " . $node->nodeType . "\n";
echo "nodeName: " .$node->nodeName . "\n";
echo "parentNode: " .$node->parentNode . "\n";
// This breaks "$node"
$dom = DOMDocument::loadXML('<root><child/></root>');
$xpath = new DOMXpath($dom);
$node = $xpath->query('//child')->item(0);
echo $node->nodeName . "\n";
$GLOBALS['dom']->removeChild($GLOBALS['dom']->firstChild);
echo "nodeType: " . $node->nodeType . "\n";
echo "nodeName: " .$node->nodeName . "\n";
echo "parentNode: " .$node->parentNode . "\n";
echo "\n";
?>
Expected result:
----------------
Properties of $node should still exists, see part1:
root
nodeType: 1
nodeName: root
parentNode:
Actual result:
--------------
Properties are gone
child
Notice: Undefined property: DOMElement::$nodeType in
/home/olaf/test/test.php on line 20
nodeType:
Notice: Undefined property: DOMElement::$nodeName in
/home/olaf/test/test.php on line 21
