In article <9012171301.AA14222@iesd.auc.dk> amanda@IESD.AUC.DK (Per Abrahamsen) writes: Emacs dumps core with signal 3 when it you press the following keys fast after each other: C-z C-\ Typing C-z invokes the suspend-emacs function. As part of doing its job, suspend-emacs restores the special terminal control characters to what they were when Emacs was invoked. Then suspend-emacs sends the TSTP signal, suspending Emacs. There is a brief time gap between resetting the terminal control characters and sending the TSTP signal when Emacs is vulnerable to being killed by the user pressing C-\. This could be solved by having Emacs intercept or ignore the QUIT signal. There might be a good reason not to do this, but I'm not aware of one. Incidentally, you can also get an interesting effect by typing "C-z C-z". -- Joe Wells <jbw@bu.edu>
