bug#7170: Crash in w32 menu (my patched version)

[Lennart Borgman]

I got a crash in w32 menus.

Unfortunately I have some patches there (that has not been included in
Emacs). So I don't know if this can be used for something. But on the
other hand I do not think this is specific to my patched Emacs, it is
just that line numbers etc are not useful. (Of course I am not sure
about this.)
