This is due to this definition:

;; Autoload this `put' since a user might use C-u C-M-x on an expression
;; containing a non-trivial `push' even before gv.el was loaded.
;;;###autoload
(put 'gv-place 'edebug-form-spec '(form)) ;So-called "indirect spec".

That's certainly not correct for the simplest forms like

(setf foo 'bar)

And it's not really correct for things like

(setf (gethash 1 table) 'bar)

either, is it?  (Although it is amusing to see the results of
(gethash 1 table), it's not really helpful.)
