Definitely a type problem.  The Obj-C front-end is playing it too lose with
types.  

main (argc, argv)
{
  char msg[100];
  int status;
  const unsigned char D.1189;
  char * msg.0;

  # BLOCK 0
  # PRED: ENTRY (fallthru)
  #   msg_3 = V_MUST_DEF <msg_2>;
  msg = "";
  msg.0_4 = &msg;               /* Mis-matched types here */
  #   VUSE <msg_3>;
  D.1189_5 = *msg.0_4;          /* And again here.  */
  return;
  # SUCC: EXIT

}

I *think* the right code is that msg.0 should have type
const unsigned char *.  In the assignment to msg.0_4 the
RHS should be casted to const unsigned char *

This is a front-end problem as far as I can tell.
