I was referring specifically to storing gc_malloc'ed pointers
on the stack, meaning that I'm calling a C++ function on a D
call stack, and storing the pointer as a local var in the C++
function before returning it to D.
The more I think about it, the more I think it has to be ok to
do. Unless D stores [ESP] to some variable at each extern(*)
function call, then the GC would have no choice but
indifference as to what side of the language boundary it was
scanning on. If it did, I imagine it would say so here:

Yes, as long as you can guarantee it stays on the stack you
should be good to go.
