Here is a simple test file:

#+begin_src emacs-lisp
;;; foo.el --- ...  -*- lexical-binding: t -*-

(defun my-foo--around-ad (f &rest args)
  17
  (apply f args))

(advice-add 'make-frame-command :around #'my-foo--around-ad)

(provide 'foo)
;;; foo.el ends here
#+end_src

Load it, then M-x unload-feature foo RET -- and after that, C-x 5 2
errors.


Michael.
