[Armedbear-devel] Strange behaviour of unexporting and defpackage

[Eitaro Fukamachi]

This is a reproducible script.

----
(defpackage unexport-test
  (:export :a))

(eval-when (:compile-toplevel :load-toplevel :execute)
  (when (find-package :unexport-test)
    (do-symbols (symbol :unexport-test)
      (unexport symbol :unexport-test))))

(defpackage unexport-test
  (:export :a))

(prin1 (nth-value 1 (intern (string :a) :unexport-test)))

#+sbcl (sb-ext:exit) #-sbcl (cl-user::quit)
----

$ sbcl --load unexport-test.lisp
:EXTERNAL

$ ccl --load unexport-test.lisp
:EXTERNAL

$ abcl --load unexport-test.lisp
:INTERNAL
