The problem with 4.0 is that it behaves completely different in this case
and the fix at expand time is too late.  After gimplification we already have

sub (i)
{
  static int C.0[1000000] = {0};
  unsigned int i.1;
  unsigned int D.1136;
  int * D.1137;
  int * D.1138;
  int array[1000000];

  array = C.0;
  i.1 = (unsigned int) i;
  D.1136 = i.1 * 4;
  D.1137 = (int *) D.1136;
  D.1138 = &array + D.1137;
  sub2 (D.1138);
}

While for 4.1 we get

sub (i)
{
  unsigned int i.0;
  unsigned int D.1282;
  int * D.1283;
  int * D.1284;
  int array[1000000];

  array = {};
  i.0 = (unsigned int) i;
  D.1282 = i.0 * 4;
  D.1283 = (int *) D.1282;
  D.1284 = &array + D.1283;
  sub2 (D.1284);
}

which is fine.
