how to figure out if an instance was created on the "stack" or on the "heap"

[aotto <aotto1968@xxxxxxxxxxx>]

Hi,

a C++ class can be created on the "stack" or on the "heap"

class A {
  int test;
}

// stack
A myA();

// heap
A* myA = new A();


Question:

it is possible (with gcc) to find out if a instance was created on a 
"stack" or on a "heap" *
