bug#21683: 25.0.50; `advice-add` doesn't work for compiled primitive functions

[Vitalie Spinu]

Hi,

Put this function into a file, compile the file and then load the file:

    
  (defun foobar ()
   (save-restriction
     (widen)))


then:

  
  (defun restrict-widen (orig-widen)
    (message "here")
    (apply orig-widen nil))
  
  (advice-add 'widen :around #restrict-widen)
  
  (foobar)



The advice is not triggered.


Eval the `foobar` definition interactively and the advice will start
working. The problem occurs only for primitive c functions. Elisp
functions are fine. It doesn't work with 24.4.1 either.
