Thanks.  It aborts here:

    INLINE int
    window_box_height (w)
	 struct window *w;
    {
      struct frame *f = XFRAME (w->frame);
      int height = WINDOW_TOTAL_HEIGHT (w);

      xassert (height >= 0);  <<<<<<<<<<<<<<<<<<<<<

Which means the value of height is non-positive.  So please go to
frame #1 and show the values of height, w->total_lines and
w->total_cols.  I suspect that they are all zero.  If that is true,
please see how did that happen, because the function make_frame was
supposed to set this window (the root window of the newly created
frame) to 10x10 dimensions, around line 385:

  /* 10 is arbitrary,
     just so that there is "something there."
     Correct size will be set up later with change_frame_size.  */

  SET_FRAME_COLS (f, 10);
  FRAME_LINES (f) = 10;

  XSETFASTINT (XWINDOW (root_window)->total_cols, 10);
  XSETFASTINT (XWINDOW (root_window)->total_lines, (mini_p ? 9 : 10));

If total_lines and total_cols get the right values here, then please
set a watchpoint on these fields, or step through the code between the
above and where it aborts, and see where they are reset to zero.

Thanks.
