Confirmed but guess what my tree combiner fixes the problem:
  # i_24 = PHI <i_9(1), 0(0)>;
<L0>:;
  D.1165_26 = (unsigned int) i_24;
  D.1166_25 = D.1165_26 + 1;
  i_9 = (int) D.1166_25;
  bar (i_9);
  D.1121_5 = D.1165_26 >> 5;
  D.1122_10 = D.1121_5 * 4;
  D.1123_11 = (int *) D.1122_10;
  D.1124_12 = array_8 + D.1123_11;
  D.1125_13 = *D.1124_12;
  D.1126_14 = (long unsigned int) D.1125_13;
  D.1127_15 = i_24 & 31;
  D.1128_16 = 1 << D.1127_15;
  D.1129_17 = D.1126_14 | D.1128_16;
  D.1130_18 = (int) D.1129_17;
  *D.1124_12 = D.1130_18;
  if (D.1166_25 != 11) goto <L0>; else goto <L2>;

Guess that means I need to work more on it.
