>Description:
This code :

      1 int main()
      2 {
      3         int * p1 = 0;
      4         int * p2 = 0;
      5
      6         /* compile with -Wall */
      7         p1, p2;
      8         delete p1, p2;
      9 }

compiled with g++ -Wall gives a warning for no effect
on line 7, but not line 8 (where the sub-expression
p1 has no effect).
