Description changed by mevenson:

Old description:
...
The code
[source:/trunk/abcl/src/org/armedbear/lisp/ArgumentProcessor.java] does
not handle &AUX arguments for CL:DEFMETHOD correctly.
After defining the APPLY-RULE generic function as such:
{{{
(defgeneric apply-rule (rule))
(defmethod apply-rule ((rule t) &aux (context (format nil "~A" rule)))
  (format nil "Applying rule '~A' in context '~A'" rule context))
}}}
then
{{{
   CL-USER> (apply-rule "1")
}}}
will fail with errors in
{{{
(defgeneric apply-rule (rule))
(defmethod apply-rule ((rule t) &aux (context (format nil "~A" rule)))
  (format nil "Applying rule '~A' in context '~A'" rule context))
}}}
