  I know I'm replying to a rather old message, but this code looked so
horrible, that I must reply.
  Firstly I think that it breaks the standard. One cannot assume that
the member variables of a struct start right at the beginning of the
struct.
  Secondly, why not just:

int main() {
  X x;
  print(&x);

  for(int i = 0; i < sz; ++i)
    x.a[i] = 0;

  print(&x);
}

  It's a lot nicer, doesn't use hacks and doesn't break the standard.
