Fixed in 4.7.0:

<bb 2>:
  D.2697_1 = rand ();
  foo_2 = D.2697_1 != 0;
  D.2698_3 = rand ();
  bar_4 = D.2698_3 != 0;
  D.2711_30 = bar_4 & foo_2;
  D.2700_9 = (int) bar_4;
  D.2699_10 = (int) D.2711_30;
  printf ("%u %u\n", D.2699_10, D.2700_9);
  D.2702_11 = rand ();
  foo_12 = D.2702_11 != 0;
  D.2703_13 = rand ();
  bar_14 = D.2703_13 != 0;
  D.2712_7 = bar_14 & foo_12;
  D.2700_19 = (int) bar_14;
  D.2699_20 = (int) D.2712_7;
  printf ("%u %u\n", D.2699_20, D.2700_19);
