bug#16502: segmentation fault with org-capture

[Nathan Froyd]

Given this initialization file, bug-init:

(require 'org)
(require 'org-capture)
(setq org-capture-templates
      '(("m" "memories" plain (file "~/memories") "%t %?")))
(global-set-key [f2] 'org-capture)

and starting emacs (24.x or emacs from git) with:

emacs -Q -l bug-init

and then repeatedly pressing the key sequence:

<F2> m C-c C-k

will eventually cause emacs to crash with a segmentation fault, or
consume vast amounts of memory, and then crash.  It typically takes
5-6 repetitions of that key sequence.

Consuming vast amounts of memory seems slightly more common with emacs
from git than, say, 24.3.

I have seen segmentation faults happen with a couple of different stacks:

The line information on this next stack does not appear to be
accurate, as the variable i is usually a null interval, and the crash
happens referencing the interval's plist:
