Hi.

First declare:

   (defclass cc-A ()
     ((a :initform "foo")))
   
   (defgeneric xx (&optional a b))
   (defmethod xx ()
     (message "default"))

And eval (xx). It works as expected.

Now add

   (defmethod xx ((obj cc-A) &optional b)
     (message "called on cc-A object"))

and eval (xx) again. It throws (wrong-number-of-arguments (1 . &rest) 0).

It used to work in emacs 24.

Thanks,

  Vitalie
