#239 assigned defect

DEFGENERIC with unsuitable :generic-function-class gives incomprehensible error

Reported by: rschlatte Owned by: rschlatte
Priority: minor Milestone: 1.6.0
Component: CLOS Version: 1.2.0-dev
Keywords: Cc:

Description

Compiling and loading the following (incorrect) file gives an error saying that foo-generic-function is not of type standard-generic-function. The real error is that foo-generic-function must be defined with (:metaclass funcallable-standard-class) to be suitable as a generic function class.

(require :clos)

(defclass foo-generic-function (standard-generic-function))

(defgeneric goo (a b)
  (:generic-function-class foo-generic-function)
  (:method (a b)
    (princ "default method")))

(print #'goo)

The attached patch would emit a full warning in defgeneric, but currently find-class does not implement correct behavior when called with 3 parameters.
