The i variable is used to count the number of stack frames printed,
but it is initialized to 0 only at the beginning of the loop, and
is not increased later in the loop. Therefore, the value of i is
always 0, resulting in the condition if (i > 40) never being true.
To ensure that i counts correctly, you need to increase the value
of i each time the stack frame is successfully printed.
