Well, maybe I'm missing something important, but isn't the dump file a
series of struct's defined as this:

    struct record_entry
    {
      struct record_entry *prev;
      struct record_entry *next;
      enum record_type type;
      union
      {
	/* reg */
	struct record_reg_entry reg;
	/* mem */
	struct record_mem_entry mem;
      } u;
    };

?  If so, then the dump file uses host's native pointers, so it is not
portable to a different host.  Right?
