Confirmed and copyrename appears to generate this which is where things appear
to start going pear-shaped. 

test_alignment (char * m)
{
  unsigned int pkt_dst$s_addr;
  int D.2017;

<bb 2>:
  pkt_dst$s_addr_8 = MEM[(struct ip *)m_2(D) + 7B].s_addr;
  if (pkt_dst$s_addr_8 == 0)
    goto <bb 4>;
  else
    goto <bb 3>;

<bb 3>:

<bb 4>:
  # D.2017_1 = PHI <1(2), 0(3)>
  return D.2017_1;
}
