Thanks for checking!

I just did my own testing and agree that this has already been fixed.  I
checked out the latest emacs-24 branch of the Git repository
(git://git.savannah.gnu.org/emacs.git) and could not reproduce the
problem.  To ensure the crash in 24.3 wasn't due to certain arguments
passed to 'configure' (e.g., -fstack-protector in the CFLAGS used by
Ubuntu), I checked out the emacs-24.3 tag, ran 'configure' with the same
arguments I used to build the tip of the emacs-24 branch, and was still
able to reproduce the crash.

Thanks,
Richard
