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.
