Args out of range with new auto-composition implementation

Args out of range with new auto-composition implementation

[Juanma Barranquero]

An error I'm getting since the auto-composition changes of a few days ago:

;;; testbug.el ;;;
(column-number-mode 1)

(defun testbug ()
  (interactive)
  (split-window)
  (other-window 1)
  (pop-to-buffer (get-buffer-create "testbug")))
;;;;;;;;;;;;;;;;;

emacs -Q -l testbug.el
C-h H
M-: (goto-char 276) <RET>   ;; or move the cursor to any auto-composed char
M-x testbug <RET>

  => "Args out of range: 274, 274"

(and the windows are not correctly painted.)

Setting a breakpoint at data.c:args_out_of_range, you get this backtrace:

I can't reproduce that bug with the latest code.  Can you?

I noticed something very similar in CVS Gnus with CVS Emacs from
yesterday.  See http://thread.gmane.org/gmane.emacs.gnus.general/67353

For now I've wrapped the problem with a condition-case in Gnus...
Definitely not the right solution, but I can enter groups now :)

Yes.  The only possibility that happens is that w->buffer is
different from current_buffer.  I've thought that when
current_column is called, the selected window is that same
as the window showing the current buffer.  But, it seems
that we can't assume that.  Perhaps that is the reason why
it uses buffer-display-table of the current buffer instead
of window-display-table as in compute_motion().

Anyway, I've just installed a workaround of not handling
automatic composition if the current buffer is not
associated with a window.

That fixes the problem. Thanks.

Do you still see the same problem with the latest code when
you disable that wrapping?

Yes.  Look at gnus-sum.el:gnus-summary-insert-line and remove the
condition-case wrapper to see the error.

Please do C-u - M-x global-auto-composition-mode RET and try
again.  If you still see "Args out of range" error, I think
it's not related to the changes for auto-composition.
