From: Jordi Gutiérrez Hermoso <jordigh <at> octave.org> To: bug-gnu-emacs <at> gnu.org Subject: 23.2; Segfault with csv-mode Date: Fri, 8 Jun 2012 12:29:46 -0400
(1) Load the following csv-mode.el: http://jordi.platinum.linux.pl/emacs-bug/csv-mode.el (2) Open the following csv file: http://jordi.platinum.linux.pl/emacs-bug/foo.csv (3) Align all fields: C-x h C-c C-a (4) Attempt to sort them: M-x csv-sort-fields <RET> In Emacs 23, this incurred an immediate crash. At bzr revno: 108512, after attempting to move the point a little (C-e, C-a, C-p, C-n, maybe C-g), I obtained the following stack trace: Program received signal SIGSEGV, Segmentation fault.

I can reproduce it quite reliably. I'm not sure I'm at the correct revision, but I just tried this again at revno 108581 with the same results. I tried 108257 (which seems to be from May 17? Not "today"?), and also got the same result. It seems to take a little while for the segfault to occur. Trying a few motion keys (C-n, C-e, C-a) seems to trigger it for me. >> (gdb) bt >> #0 0x0000000000438b03 in handle_face_prop (it=0x7fffffffb0c0) at xdisp.c:3693 > > In frame 0, can you show what does the following GDB command print? Sure thing: Program received signal SIGSEGV, Segmentation fault. 0x0000000000438649 in handle_face_prop (it=0x7fffffffb180) at xdisp.c:3689 3689 = (it->current.overlay_string_index >= 0 (gdb) p it->current $1 = { pos = { charpos = 1, bytepos = 1 }, overlay_string_index = 1935, string_pos = { charpos = 0, bytepos = 0 }, dpvec_index = -1 } Thank you for your interest, - Jordi G.

If not, this huge number is probably garbage, and is the cause for the segfault. Btw, when I tried your recipe, Emacs asked me about the column to sort by, which was not in your recipe. Can you double-check if your recipe is 100% correct and does not omit any important details?

It's an overlay with a before-string or an after-string property. You should be able to see that with "M-x describe-text-properties RET", I think, as well as in the code of the mode you are using. > > Btw, when I tried your recipe, Emacs asked me about the column to sort > > by, which was not in your recipe.

The worst problem I see is some issue with cursor positioning on the long first line in the buffer. I will try fixing that, in the hope that doing so will solve whatever reasons for your crashes.

Heh, it looks like we never had more than 16 overlay strings loaded at the same time in the last 4.5 years since the offending code was introduced (in Emacs 22.2)... csv-mode has some bug whereby no less than 2479 overlay strings are present at buffer position 1, which triggers the bug. Fixed in revision 108625 on the trunk.
