My testcase is quite large, sorry: 
 
struct tr { 
  int neigh[2]; 
}; 
tr * data; 
tr & func(int index) { 
  return data[index]; 
}; 
 
void x(int); 
void check_triangle_neighbours() { 
  for (int tr1 = 0; tr1 < 1; ++tr1) { 
      int c1 = 0; 
      for (int n = 0; n < 2; ++n) { 
        c1 += func(tr1).neigh[n]; 
      }; 
      x(c1); 
  }; 
};
