bug#593: Emacs.app crash

[Gilbert Harman]

Using the CVS version from about 7 am today on a Mac iMac running OS
10.5.4 to produce Emacs.app.
I opened my .emacs file and used control-n to move down several lines
at which point emacs froze.
What follows is the backtrace from gdb followed by the contents of the
file I was editing.

bug#595: [Emacs.app dev]: Emacs.app crash

This is no time. Over the day there are two or three dozen zones that  
have "7 am." What is your zone's distance to UTC? Or do you know your  
time zone and whether you have daylight savings time?


Compiled on Tiger, Mac OS X 10.4.11, with sources from around 13:00  
UTC Emacs.app works OK. Except: tabbar lets it crash.
