recursion using only heap area

Question

Are there examples of recursion using only heap area?

Answer 1

You could do something crazy like malloc a new area, turn off interrupts and just about everything else (not possible on many systems) and set your stack pointer to that malloc area. You are technically still playing with a stack, but that stack location is now on the heap. Not a good idea to do, but it can work on some embedded type systems where you have this level of control.
