Don't needlessly intern symbols, #'function-arglist, #'cl-function-arglist 2009-09-20 Aidan Kehoe <kehoea@parhasard.net> * help.el (function-arglist): Show the double-quotes in the sample output, correctly. Bind print-gensym to nil, now we're using uninterned symbols. Don't #'mapcar + #'intern to create uppercase symbols, use #'loop and #'make-symbol instead. * cl-macs.el (cl-upcase-arg): Don't intern the upcased symbols we're using for cosmetic reasons. Trust #'true-list-p in #'cl-function-arglist to detect circularity. (cl-function-arglist): Bind print-gensym to nil, now we're printing uninterned symbols and would prefer to avoid the gensym syntax. (cl-transform-lambda): Only add the Common Lisp lambda list: argument information when that differs frmo the normal argument information.

/* code is all from loser.c and loser.el by Mly

Copyright (C) 2002 Richard Mlynarik <mly@pobox.com>

This is part of XEmacs

Compile this file.  Run it in the background giving it a command line
argument PORT which is a positive integer 1024 < PORT < 32768 (avoid the
numbers assigned in /etc/services).

Then start up a fresh (you're going to crash) XEmacs.  Execute the following

(defun lose (port)
  (interactive "nUrk: ")
  (require 'comint)
  (while t
    (condition-case e
        (let* ((name "*lose*")
	       (b (get-buffer-create name)))
          (switch-to-buffer b)
          (comint-mode)
          (comint-exec b name (cons "127.0.0.1" port) nil '())
          (process-send-string (get-buffer-process b) "\377\373\001")
          (process-send-string (get-buffer-process b) "\377\373\001"))
      (error (message "URK: %s" e)) (sit-for 1))))

Then M-x lose RET PORT RET and you lose big (in XEmacs 21.1, anyway).
Note: the error messages are proper functioning.  What should eventually
happen after a number of SIGPIPEs is that you get a SIGSEGV and life is
bad and XEmacs is dead.
