defmethod multiple specializers with one argument

[Reinout Stevens]

When defining a method and you try to have more then 1 typespecializer SBCL does not complain. It does complain when trying to execute that method

(defclass animal ()
  ())

(defclass person ()
  ())

(defmethod foo ((arg animal person))
   arg) ;;this works and does not give an error/warning

(foo (make-instance 'person)) ;;doesnt work, no applicable method

version:
SBCL 1.0.29.11.debian and
SBCL 1.0.31 and
SBCL 1.0.34
