I have a COM interface that is dynamically created using

One of the functions returns an interface. It is just a value

If I use it as a pointer in to the the D interface equivalent,
it crashes as the value is not pointing to anything valid.
What do these values represent? I tried to use QueryInterface
from the class who's function provides the "COM interface" but
it returns interface not supported.
So, I have one dynamic COM interface that I initialize
properly and can call it's functions and all the ones I tested
work fine. Some of those functions returns interfaces. If I
try to call the functions on those interfaces, the app crashes.
How to I get the interfaces the return values represent? Or
for that matter, the functions that ask for an interface, what
do I pass? Passing or using the generated D interfaces does
not work.
I'm sorry, but probably you should read something like this[1]
first, this tech(COM) is beyond D, so you must understand how
it works before trying it in D.

Reading that tells me nothing about how to get a dynamic COM
interface of a dynamic COM interface... but I guess you knew
that, didn't you? I'm sorry, but you are an ____.
