bug#16326: 24.3.50; Emacs crashes when C-c C-c to end the capture of an Org note

[Sebastien Vauban]

Hello,

First, let me thank an happy new year for you all, the Emacs developers!

Second, I just downloaded this morning a new version of Emacs (Windows
binary), compiled by Dani on the 29th of December.

It is quite unstable for me: it crashed no less than 4 times over
a couple of hours...

    Note -- Up to now, I was using r114715 (from 2013-10-19). That one
    was quite stable: almost no crash at all. I tried updating this
    morning to see if the Org display performance problem (because of
    the display of UTF-8 characters) was solved with new versions. That
    is well solved (thanks to a workaround, IIUC).

I had no time to try debugging the first crashes. Now, I can afford
looking at it.

Here is the backtrace:

This is almost certainly a duplicate of bug #16265, which was fixed
yesterday.  Try to find a newer binary, or set cache-long-scans to nil
as a workaround.
