You SHOULD post the code of the function that causes the message.  But
consider:

int compare(int a, int b)
{
   if (a < b)
      return -1;
   else if (a > b)
      return 1;
}

There are three return points in this function, the two return
statements and the "}" that ends the function.  Depending on the
values passed to the function when it is called, it might return -1,
it might return 1, or it might hit the "}" and return ???  That final
possibility will happen if a and b are equal.
