| 5 This is part of XEmacs | |
| 6 | |
| 7 Compile this file. Run it in the background giving it a command line | |
| 8 argument PORT which is a positive integer 1024 < PORT < 32768 (avoid the | |
| 9 numbers assigned in /etc/services). | |
| 10 | |
| 11 Then start up a fresh (you're going to crash) XEmacs. Execute the following | |
| 12 | |
| 13 (defun lose (port) | |
| 14 (interactive "nUrk: ") | |
| 15 (require 'comint) | |
| 16 (while t | |
| 17 (condition-case e | |
| 18 (let* ((name "*lose*") | |
| 19 (b (get-buffer-create name))) | |
| 20 (switch-to-buffer b) | |
| 21 (comint-mode) | |
| 22 (comint-exec b name (cons "127.0.0.1" port) nil '()) | |
| 23 (process-send-string (get-buffer-process b) "\377\373\001") | |
| 24 (process-send-string (get-buffer-process b) "\377\373\001")) | |
| 25 (error (message "URK: %s" e)) (sit-for 1)))) | |
| 26 | |
| 27 Then M-x lose RET PORT RET and you lose big (in XEmacs 21.1, anyway). | |
| 28 Note: the error messages are proper functioning. What should eventually | |
| 29 happen after a number of SIGPIPEs is that you get a SIGSEGV and life is | |
| 30 bad and XEmacs is dead. | |
