Can you give an example of stack overflow in C++?

Question

Can you give an example of stack overflow in C++? Other than the recursive case:

void foo() { foo(); }

Answer 1

Here's one that might happen in practice:

int factorial(int x) {
  return x == 0 ? 1 : x * factorial(x-1);
}

This overflows the stack for negative x. And, as Frank Krueger mentioned, also for too large x (but then int would overflow first).
