<bb 10>:
  # i.21_754 = PHI <i.21_1090(10), 0(9)>
  # i.21_484 = PHI <i.21_1090(10), 0(9)>
  D.4090_71 = b[i.21_754];
  x[i.21_754] = D.4090_71;
  D.4345_1088 = (unsigned int) i.21_484;
  D.4346_1089 = D.4345_1088 + 1;
  i.21_1090 = (int) D.4346_1089;
  if (n.17_753 > i.21_1090)
    goto <bb 10>;
  else
    goto <bb 11>;

seems to work with 4.4.
