Static arrays point to memory on the stack, inside an aggregate type on 
the heap, or inside the static data area. In the stack case, you can use 
this strategy:

extern (C) void* thread_stackBottom();

bool isLocatedOnStack(T)(T[] arr) {
  int i;
  void* top = &i;
  auto bottom = thread_stackBottom();
  return arr.ptr >= min(top, bottom) && arr.ptr <= max(top, bottom);
}

When you get to GC-allocated stuff, there's no way to tell. Static data, 
I'm not sure.

This probably isn't what you want, though.
