Though -O3 generates much larger code.  What needs to be done is that one thing
really:
      if (j < k)
        a[i] = 1;
      else
        a[i] = j;

Needs to be transformed into:
      if (j < k)
        tmp = 1;
      else
        tmp = j;
      a[i] = tmp;

And then it should work correctly.  I think there is already a bug about that.
