int i;
int* p1 = &i;
int* p2 = new int;
assert(!onHeap(p1));
assert(onHeap(p2));

@juanchopanza There kind of is … override `operator new` (and maybe `malloc`) to introduce your own bookkeeping. – Konrad Rudolph Jun 13 '14 at 15:54

@KonradRudolph If the pointer is allocated by a 3rd-party library... – user1899020 Jun 13 '14 at 15:55

@user1899020 Depending on how you link the library that might still work (but, yes, it probably won’t). – Konrad Rudolph Jun 13 '14 at 15:56
