If a COM property set is called on an overloaded object that was created by a COM method call, memory leaks (as identified by an ever growing DLLHOST memory size under the ISAPI filter).  This does not happen if you use the functional COM interface.

This will leak:

$xml = new COM("MSXML.DOMDocument");
$element = $xml->createElement("test");
$element->text = str_repeat("this is a text string!", 100);
$element->Release();
$xml->Release();

but this doesn't:

$xml = new COM("MSXML.DOMDocument");
$element = com_invoke($xml, "createElement", "test");
com_set($element, "text", str_repeat("this is a text string!", 100));
com_release($element);
$xml->Release();

I did confirm that the bug exists in the current HEAD branch, but was unable to confirm the fix as the com_invoke call would fail.
