If the position of a window's cached point is deleted, use buffer point instead
src/ChangeLog addition:
2014-06-17 Aidan Kehoe <kehoea@parhasard.net>
* extents.h:
* window.c:
* window.c (unshow_buffer):
* window.c (Fset_window_buffer):
Use extents, rather than markers, for the window buffer point
cache, so that when the text containing that window buffer point
is deleted, the window display code uses the buffer's actual point
instead of the position that the marker had been moved to.
Fixes Michael Heinrich's problem of
http://mid.gmane.org/6zr42uxtf5.fsf@elektra.science-computing.de ,
introduced by Ben's patch of
https://bitbucket.org/xemacs/xemacs/commits/047d37eb70d70f43803 .

19 Commentary: |
| 1231 | 20 |
| 21 Compile this file. Run it in the background giving it a command line | |
| 22 argument PORT which is a positive integer 1024 < PORT < 32768 (avoid the | |
| 23 numbers assigned in /etc/services). | |
| 24 | |
| 25 Then start up a fresh (you're going to crash) XEmacs. Execute the following | |
| 26 | |
| 27 (defun lose (port) | |
| 28 (interactive "nUrk: ") | |
| 29 (require 'comint) | |
| 30 (while t | |
| 31 (condition-case e | |
| 32 (let* ((name "*lose*") | |
| 33 (b (get-buffer-create name))) | |
| 34 (switch-to-buffer b) | |
| 35 (comint-mode) | |
| 36 (comint-exec b name (cons "127.0.0.1" port) nil '()) | |
| 37 (process-send-string (get-buffer-process b) "\377\373\001") | |
| 38 (process-send-string (get-buffer-process b) "\377\373\001")) | |
| 39 (error (message "URK: %s" e)) (sit-for 1)))) | |
| 40 | |
| 41 Then M-x lose RET PORT RET and you lose big (in XEmacs 21.1, anyway). | |
| 42 Note: the error messages are proper functioning. What should eventually | |
| 43 happen after a number of SIGPIPEs is that you get a SIGSEGV and life is | |
| 44 bad and XEmacs is dead. | |
