Could you send a backtrace with non byte-compiled code?

Hi Nicolas,

The problem is that the byte code comes from Python mode.

I solved the problem with this:

$ diff -uw contrib/lisp/org-eldoc.el contrib/lisp/org-eldoc.el

--- contrib/lisp/org-eldoc.el 2016-02-29 11:13:22.330099500 +0100

+++ contrib/lisp/org-eldoc.el 2016-07-04 07:11:10.466144400 +0200

@@ -155,7 +155,8 @@

(string= lang "golang")) (when (require 'go-eldoc nil t)

(go-eldoc--documentation-function)))

(t (let ((doc-fun (org-eldoc-get-mode-local-documentation-function lang)))

- (when (fboundp doc-fun) (funcall doc-fun))))))))

+ (when (or (and (symbolp doc-fun) (fboundp doc-fun))

+ (functionp doc-fun)) (funcall doc-fun))))))))

;;;###autoload

(defun org-eldoc-load ()

In python.el, one can find this around line 5129:

(if (null eldoc-documentation-function)

;; Emacs<25

(set (make-local-variable 'eldoc-documentation-function)

#'python-eldoc-function)

(add-function :before-until (local 'eldoc-documentation-function)

#'python-eldoc-function))

which stores byte code in eldoc-documentation-function, which makes

fboundp fail because the object is not a symbol. However it is a function.

Regards,

Fabrice
