I did that in x, nd and w32.  However, I can't compile on w32, can someone just double check that it compiles?

Thanks.

Hi,

starting with emacs -Q, when I eval the following expression:


(let* ((pop-up-frames t))
  (define-key (lookup-key global-map [menu-bar]) [foo]
    '(menu-item "Foo" ignore :enable (file-exists-p "http://www.foo.com")))
  (setq default-directory "/")
  (make-frame))


Emacs crashs.

I was able to produce the crash on different hosts.

I can provide a backtrace if needed.
