I'll have to take your word for it.  The tree structure and how it
works is an area I don't know as well as I'd like.

I meant from a code generation standpoint.  What do you expect to do with
a pointer to a stack slot that holds the address of the object?

Regardless, I've tweaked the compiler to shove the pointer into a
stack slot, then give you back the address of that stack slot.  I don't
have any way to test whether or not the generated code is actually
correct though.
