--- Comment #4 from Sergei Trofimovich <slyfox at inbox dot ru> ---
Shortened even more by removing operator overload:

 int b;
 int c;
 void g() {
  for (int f; f; f++) {
    int d = 0;
    for (int e = -1; e <= 1; e++) {
      int a = f + e;
      if (a)
        d = *(&c + a);
    }
    *(&b + f) = d;
  }
 }
