Re: [O] Frequent crashes of Emacs 24 on Mac OS X 10.7.3 due to org-mode

[Marius Hofert]

Dear Martyn,

thanks for helping.

3) 7.7: As far as I remember, I've been there.
2) 24.0.94.1: I've definitely been there -- didn't sort it out. I even wanted to
build Emacs on my own to see if that has an influence. But I obtained some
errors due to missing tools (starting with libgif/libungif but after I installed
that many other things appeared) and others also reported that it is not too
easy under Lion
(http://readystate4.com/2011/04/19/installing-latest-command-line-emacs-on-mac-os-x/).
1) .emacs: I've never seen .emacs in org-babel, sounds interesting. What I 
typically do is some kind of "bisection" procedure to find the the bug (comment 
out half of the code, test, find the buggy half...).

The part of my .emacs that concerns org-mode is (of course the problem could be
elsewhere but my suspicion would be it's in here):

Just a remark: The problem has nothing to do with Sweave (I just use Sweave for
some weeks now and the crashes I had long before). Last week a colleague
wanted to use my laptop and as soon as he hit the first button, Emacs
crashed (-- very annoying -- this was when I decided to try to track the 
problem down). That's why I have trouble figuring out what it is (and I was 
quite
"happy" to see "org-mode" popping up through Console.app as a reason -- at least
that gives a chance to track it down).

I'll further explore and get back to you (and the guys from Emacs bug tracker
who also are interested in this).


Cheers,

Marius

PS: I used the same .emacs on Ubuntu 11.10, only one line was changed (the
default font being changed from Menlo -- which is Mac-specific). I never
experienced a crash (although I just tried it for some hours, so I can't tell
for sure).
