After running for perhaps a day or two, emacs crashed in
ns_set_vertical_scroll_bar.  I'm not sure how to reproduce it, but I
still have the lldb session open so I can get more info if desired.
Unfortunately, I don't have gdb installed so I can't use xbactrace, but
it doesn't look like that would be very useful anyway.

OS X 10.9.5 in case it matters.

ns_set_vertical_scroll_bar is not at nsterm.m:3767.  When did you check out
your sources?

Right before I built, so on 2014-11-05.  I’m not sure the exact commit I
checked out, but it would have been one of the commits below (almost
certainly the last).  I’m using the git mirror, so I don’t know the bzr ids.

Those are messages from the trunk, but your subject says 24.4.51.  Are you
sure you know what version you use and/or build?

A fair question.  :)  After it crashed I started using the emacs-24 branch
again.  I should have cut out all that junk from the bug email, I’m very
sorry.  I probably wasted a bunch of your time.
