Fixed.  This is with current CVS mainline:

$ cat pr14470.c.t08.gimple

;; Function main (main)

main ()
{
  static int C.0[1025] = {1024};
  int d.1;
  int D.1122;
  int D.1123;
  int D.1124;
  int D.1125;
  int D.1126;
  int t[1025];
  int d;

  t = C.0;
  d = 0;
  d.1 = d;
  D.1122 = t[d.1];
  d = D.1122;
  D.1123 = D.1122 + 1;
  t[d.1] = D.1123;
  D.1124 = t[1024];
  D.1125 = t[0];
  printf (&"%d %d %d\n"[0], d, D.1125, D.1124);
  D.1126 = 0;
  return D.1126;
}
