----------------
Shouldn't this access have a size of 4, and an access for c->x[2] have a size 
of 4 and a specific offset and c->x[j] have a size of 12 and an offset of zero? 
Why does this list a size of 16?

In any case, please add tests for:

  int *bar2(C *c) {
    return c->x;
  }

  int bar3(C *c) {
    return c->x[2];
  }

  int bar4(C *c, int j) {
    return c->x[j];
  }
