We now get:
  # i_7 = PHI <i_3(1), 0(0)>;
<L0>:;
  i_3 = i_7 + 1;
  bar (i_3);
  D.1284_13 = *array_8;
  D.1285_14 = (long unsigned int) D.1284_13;
  D.1286_15 = i_7 & 31;
  D.1287_16 = 1 << D.1286_15;
  D.1288_17 = D.1285_14 | D.1287_16;
  D.1289_18 = (int) D.1288_17;
  *array_8 = D.1289_18;
  if (i_3 != 11) goto <L0>; else goto <L2>;

This is semi fixed for bounds less than 32.
trying with 37, we get the same old crap.
