Yes.. it's a remainder from before there was any dynamic memory
allocation, and which I haven't come around to fix yet. Please just
put in a declaration (and obey it..) until I can get it fixed.

  (defun silly-fn (&rest objects)
    (declare (dynamic-extent objects))
    (mapcar #'+ objects))

should work.
