another compiler bug?

[Mitsukai]

What is the sence of adding 2 pointers?

i will give you a simple example.

struct SA
{
int size;
int* data;
};

void FA(const struct SA& PA, const int new_size)
{
  int* tmp_data = new int[new_size];
  memcpy(tmp_data, PA.data, (PA.size > new_size) ? new_size : PA.size * sizeof(int));
  delete[] data;
  PA.data = tmp_data;
  PA.size = new_size;
}

int main(void)
{
  SA LA;
  LA.data = new int[LA.size = 1234];
  int* LB = LA.size;
  FA(LA, 4321);
  LB += LA.data; // we now have position of the added space
  delete[] LA.data;
}
