You are correct: map.xsize = 50, map.ysize = 35

It is a transport on its way to (23, 32) under AI control. Why did it go
to (27,35)?

Other variables set inside the do loop:

 last_tile = FALSE;
 waypoint_x = 23
 waypoint_y = 32
 penemy = NULL
 punit->moves_left = 3
 dest_x = 23
 dest_y = 32
 success is undefined

It was called from unittols.c:

  if (activity==ACTIVITY_GOTO) {
    if (!punit->ai.control && (!is_military_unit(punit) ||
       punit->ai.passenger != 0 || !pplayer->ai.control)) {
/* autosettlers otherwise waste time; idling them breaks assignment */
/* Stalling infantry on GOTO so I can see where they're GOing TO. -- Syela
*/
      (void) do_unit_goto(punit, GOTO_MOVE_ANY, TRUE);
    }
    return;
  }

This piece of code is kind of hairy, but I still don't know why it should
bug. The goto destination seems ok.
