As far as I can tell it is still allocated. I am using vld (Visual Leak Detector) which in my experience usually don't report any false leaks. If I comment out the deletion of the parser I get 154 memory leaks. Also commenting out XMLPlatformUtils::Terminate() gives 3410 leaks.

The memory is owned by the DOMDocument, which is owned by the parser (as you used getDocument instead of adoptDocument to obtain it). Can you check if the memory is still allocated after the "delete parser;" statement?
