This time I wasn't editing but just moving around the buffer rapidly, holding down keys like C-n, C-p, C-f, C-v etc. until Emacs didn't respond anymore, then C-g, upon which Emacs aborted. The session was not quite as old as the previous one, 9-10 hours. I had tried unsuccessfully to induce the crash several times earlier in the session. One thing that may play a role is that, when this induced abort occurred, the machine was running another program that was consuming a large amount of CPU cycles, which made Emacs (even more) sluggish (though when the crash that prompted my OP occurred I wasn't running that other program, yet Emacs was sluggish anyway). And indeed, I was just able to induce the abort again with the same procedure: while another CPU-intensive program was running, I moved point with C-n etc. rapidly around in a Gnus buffer, until there was no response, hit C-g (this time 3 times in succession; I can't remember if that was the case with the other crashes), and Emacs aborted, with the same backtrace. This time the session was 2-3 hours old. I then immediately tried to induce the crash again with a fresh session under otherwise identical conditions, but so far it hasn't crashed. If I do get another crash, I'll leave the process running again. Steve Berman
