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

This example shows uncontrolled recursion. Eventually, the stack spaced allocated to this process will be completely overwritten by instances of bar and ret...

int foo( int bar )
{
    int ret = foo( 42 );
    return ret;
}
