&REST variable OBJECTS must be dynamic-extent.

Hello,

It seems sometimes having a &rest variable in a function causes a
strange error. Is this a known issue? It's kind of irritating :).

I added this silly function:

*** los0.lisp	15 Apr 2005 07:04:24 -0000	1.38
--- los0.lisp	17 Apr 2005 15:51:59 -0000
***************
*** 16,21 ****
--- 16,25 ----
  (provide :los0 :load-priority 0)
  
  (require :common-lisp)
+ 
+ (defun silly-fn (&rest objects)
+   (mapcar #'+ objects))
+ 
  (require :x86-pc/all)
  (require :x86-pc/io-space)
  (require :x86-pc/ne2k)

and I get this error:

Error in function LISP::ASSERT-ERROR:
   &REST variable OBJECTS must be dynamic-extent.
   [Condition of type COMMON-LISP:SIMPLE-ERROR]
