We don't generate _any_ fields for packet, but the memcmp is folded to

<bb 2>:
  p.0_2 = (const unsigned char * {ref-all}) p_1(D);
  D.1186_3 = *p.0_2;
  D.1187_4 = (int) D.1186_3;
  D.1188_5 = (const unsigned char * {ref-all}) &pkt_unaligned.packet;
  D.1189_6 = *D.1188_5;
  D.1190_7 = (int) D.1189_6;
  D.1184_8 = D.1187_4 - D.1190_7;
  return D.1184_8;

taking the address of the missing field.  This has gone "latent" on the
trunk by not generating subvariables for PTA anymore.
