Smaller testcase, without uninitialized variables too:

enum JSOp
{
  JSOP_GETELEM = 5,
  JSOP_LIMIT
};
extern void g ();
void
f (char *pc, char *endpc, int format, char ***fp, enum JSOp op)
{
  while (pc <= endpc)
    {
      if ((fp && *fp && pc == **fp) || pc == endpc)
        {
          if (format == 1)
            op = (JSOp) 256;
          else if (format == 2)
            op = (JSOp) 257;
          else
            op = JSOP_GETELEM;
        }
      if (op >= JSOP_LIMIT)
        {
          if (format)
            g ();
        }
    }
}
