I agree with Tim about removing the ptr_ members, but not about
marshalling them as 0xfeedb0b0.
I wouldn't be surprised the NT unmarshalling code does actually
implement the NDR spec for nonunique pointers: if the same opaque
value is passed for two different pointers then they're meant to be
combined into a pointer to the same object on the server, and the
referent of the pointer is only marshalled once.
So I think it would be equally easy and more reliable for us to send
the bottom 32 bits of the local pointer value.
If it's already been discovered not to do that then I will just blush
and crawl back into my cube. ;-)
