--- Comment #46 from Kaz Kylheku <kkylheku at gmail dot com> ---
C pseudocode in light of previous comment:

   double abused_fortran_fn(double x, double y, char str[1], int len)
   {
      if (len != 1)
        return abused_fortran_fn(x, y, str, 1); /* full call, not tail! */

      return tail_call_sibling(x, y, str, len);  
   }
