Getting lots of Emacs crashes

Getting lots of Emacs crashes

[Noah Slater]

Hello,

I'm getting a lot of Emacs crashes recently using Org. Is there any
way I can help to debug why this is happening?

Thanks,

What version of Org are you using?  What happens when Emacs crashes?

Best,
Richard

You can open Emacs with --debug-init and take a look to *Messages* 

Good luck.

I managed to crash Emacs yesterday too, refiling an Org task. I was
pointed to this url with a recipe to extract usefull information from
the backtrace:

,----
| https://www.gnu.org/software/emacs/manual/html_node/emacs/Crashing.html
`----

It did not work in my case though, since I seem to have a 'stripped
binary' (I never heard that before), but if it works for you, you can send
the converted backtrace to emacs-bugs (M-x report-emacs-bug).

Noah,

You might consider running emacs under a debugger. It will trap the crash and then you can ask where it happened, i.e. a stack trace. The information might be of more interest to an emacs developer than to you.

GNU software should not crash. From the emacs info (a description of a typical crash):
    If Emacs accesses an invalid memory location ("segmentation fault"), or
    exits with an operating system error message that indicates a problem
    in the program (as opposed to something like "disk full"), then it is
    certainly a bug.
The stack trace (along with all the other information that belongs in a bug report) can be very helpful.

Using Org version: release_8.3beta-38-gbaa2c5

$ emacs --version

GNU Emacs 24.4.50.1

$ emacs --debug-init

Fatal error 11: Segmentation fault/usr/local/bin/emacs: line 2: 18940
Abort trap: 6
/usr/local/Cellar/emacs/HEAD/Emacs.app/Contents/MacOS/Emacs -nw "$@"

(Here I ran org-agenda, and it segfaulted.)

I tried the above command again, and Emacs does not segfault. However,
this time, I go to mark an Org item as done, and Emacs uses up 100%
CPU.

So I try this again, but I use dtruss -p PID to get a trace.

What I do here is that I open Emacs, set the trace running, then open
the agenda, move to the item, press "t" to bring up the change state
menu, then hit "d" for DONE.

That's when Emacs hangs, and this is the trace from pressing "d":

And then just gettimeofday messages forever.

Any clue?

Is there anything else I could provide that would help? It's still
happening to me occasionally.

An ECM for the infloop could help. If it segfaults, however, it is
probably outside of Lisp scope and you should report it to the Emacs
development team.

Thanks. I have done that now. They told me to upgrade my Emacs. I have
done so. We'll see what happens. :)
