crash on MacOSX

[Liang Wang]

Hi,

I build latest trunk (--with-ns) on Mac OS X 10.7.4 but it fails to start.

Error message is

~/src/emacs/trunk$ ./nextstep/Emacs.app/Contents/MacOS/Emacs -Q
Arithmetic error

Here is backtrace.

~/src/emacs/trunk$ gdb --args ./nextstep/Emacs.app/Contents/MacOS/Emacs -Q
