Help with org related crash on OpenBSD

Help with org related crash on OpenBSD

[Aaron Bieber]

Hola,

I am trying to track down an issue where emacs hangs on OpenBSD when
using org-capture. I happens with org 9.1.2 and 8.2.10 in emacs
25.3.1.

It seems that 3 out of 4 times, emacs completely hangs when adding a
Todo. I have tried setting (toggle-debug-on-quit) and
(toggle-debug-on-error), but once the hang happens emacs becomes
completely unresponsive. The one time that it doesn't hang, it takes
around 3 or 4 seconds to actually open up the gtd.org file.

I can't reproduce on non-OpenBSD systems

The config is fairly simple:

(require 'org)

(setq org-directory "~/new_org")
(setq org-agenda-files (file-expand-wildcards "~/new_org/*.org"))
(setq org-journal-dir "~/new_org/journal/")
(setq org-mobile-directory "~/new_org/MobileOrg")
(setq org-log-done 'time)

(setq org-capture-templates
      `(("t" "Todo"
         entry (file+headline "~/new_org/gtd.org" "TODOs")
         "* TODO %?\n  :PROPERTIES:\n  :LOGGING: TODO(!) WAIT(!) DONE(!) CANCELED(!)\n  :END:\n")
        ("j" "Journal"
         entry (file+olp+datetree "~/new_org/journal-%Y-%m.org")
         "* %?\nEntered on %U\n  %i\n  %a")))

(global-set-key "\C-cc" 'org-capture)
(global-set-key "\C-cl" 'org-store-link)
(global-set-key "\C-ca" 'org-agenda)
(global-set-key "\C-cb" 'org-iswitchb)

Any suggestions would be greatly appreciated!

Cheers,
Aaron

Sorry for the repeat. Forgot to copy the list the first time.

​Instrumenting 'org-capture' with edebug might be of some assistance. This
should at least allow you to step through org-capture and see where emacs
is hanging.

In addition to the edebug suggestion, you might try these two (three?) as well:

If it's emacs that's hanging, then `strace -p <pid>' might give a hint,
although it's probably better to run emacs under gdb as described in

  https://www.gnu.org/software/emacs/manual/html_node/emacs/Checklist.html#Checklist

That can get hairy though.

If it's org-capture that's hanging, then setting debug-on-quit to t and pressing C-g when
you get a hang might give you a backtrace.
