New Comment:
Is there anything I can do to get a confirmation on this? I tried #php
on several networks, but they referred me to Freenode, where #php was
full.

Err, my apologies for not cleaning up the path names. An oversight on my
part.

Description:
------------
We have custom XML document and element classes that extend the original
DOMDocument and DOMElement classes for convenience. There is a class
that uses an instance of XmlElement obtained via a callback specified at
construction time. That XmlElement works fine and stays that way.
However, when we get its ownerDocument outside of the closure, the
result is not an XmlDocument but a DOMDocument. I cannot see a single
reason why.
I tried several options, and it only seems to happen with that closure.
I have checked versions 5.3.1, 5.3.2, 5.3.3 and now the latest 5.3.4
snapshot compiled with './configure && make'.
Test script:
---------------
http://codepad.org/hvrNh86K
The original code uses a lot of namespaces and extends XmlDocument, but
this is a much more minimal test case. Also try the "Uncomment this"
code to see what /does/ work.
Expected result:
----------------
*** Calling the callback directly...
dom-fail.php:110: $container: XmlElement: <div id="content"/>
dom-fail.php:111: $container->ownerDocument: XmlDocument; debug:
object(XmlDocument)#2 (0) refcount(1){
}
*** Calling callback from constructor()...
dom-fail.php:110: $container: XmlElement: <div id="content"/>
dom-fail.php:111: $container->ownerDocument: XmlDocument; debug:
object(XmlDocument)#2 (0) refcount(1){
}
*** In constructor, after check on $container:
dom-fail.php:95: $container: XmlElement: <div id="content"/>
dom-fail.php:96: $container->ownerDocument: XmlDocument; debug:
object(XmlDocument)#2 (0) refcount(1){
}
SUCCESS!
Actual result:
--------------
*** Calling the callback directly...
dom-fail.php:110: $container: XmlElement: <div id="content"/>
dom-fail.php:111: $container->ownerDocument: XmlDocument; debug:
object(XmlDocument)#2 (0) refcount(1){
}
*** Calling callback from constructor()...
dom-fail.php:110: $container: XmlElement: <div id="content"/>
dom-fail.php:111: $container->ownerDocument: XmlDocument; debug:
object(XmlDocument)#2 (0) refcount(1){
}
*** In constructor, after check on $container:
dom-fail.php:95: $container: XmlElement: <div id="content"/>
dom-fail.php:96: $container->ownerDocument: DOMDocument; debug:
object(DOMDocument)#2 (0) refcount(1){
}
