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. | |
