Invalid already at gimple dump:

foo (unsigned int i)

{

  <unnamed-unsigned:7> * D.1723;

  <unnamed-unsigned:7> D.1724;

  <unnamed-unsigned:7> D.1725;

  <unnamed-unsigned:7> D.1726;



  D.1723 = &arr[i].n;

  D.1724 = arr[i].n;

  D.1725 = D.1724;

  D.1726 = D.1725 + 1;

  *D.1723 = D.1726;

}

Obviously, taking address of a bitfield is wrong.
