Hmm, we do get something different on the trunk:
bar ()
{
  struct example * ex1.0;

<bb 2>:
  ex1.0 = ex1;
  ex1.0->a = 1;
  ex1.0->b = 2;
  ex1.0->c = 3;
  if (ex1.0->b != 2)
    goto <bb 3>;
  else
    goto <bb 5>;

<bb 3>:
  link_error ();
  if (ex1->c != 3)
    goto <bb 4>;
  else
    goto <bb 5>;

<bb 4>:
Invalid sum of incoming frequencies 5123, should be 6216
  link_error () [tail call];

<bb 5>:
Invalid sum of incoming frequencies 11093, should be 10000
  return;

}
