[-- Attachment #1: Type: text/plain, Size: 1042 bytes --]

Hello,

I'm trying to build a DEBUG.org that makes it easy to share MWEs of bugs I run across in Emacs packages. I'd like it to load the latest Org mode by default. Then for any given bug I load the needed packages, configure them, and demonstrate the bug.

Right now when I run the attached file, the first time I run it everything appears to work correctly. It installs Org from melpa into a temporary elpa folder, and the output of

#+BEGIN_SRC emacs-lisp :results value :noweb yes
<<init_emacs>>
<<init_org>>
(org-version nil t)
#+END_SRC

is:

#+RESULTS:
: Org mode version 9.3.6 (9.3.6-4-gdfa7a3-elpaplus @ /home/kdm/.emacs.d/DEBUG/elpa/org-plus-contrib-20200217/)

But when I load the file a second time in a clean emacs session (i.e. /usr/bin/emacs -Q ~/.emacs.d/DEBUG.org & ), then the Org version is incorrect, and I see:

#+RESULTS:
: Org mode version 9.1.9 (release_9.1.9-65-g5e4542 @ /home/kdm/.emacs.d/DEBUG/elpa/org-plus-contrib-20200217/)


Can anyone explain what I'm doing incorrectly in the attached file?

Thanks,

  -k.

Run this debug Org file in a clean emacs session with:

/usr/bin/emacs -Q ~/.emacs.d/DEBUG.org & 

Initialize Emacs to reproduce this bug. Press `C-c C-c` in the Org Babel block below.

#+BEGIN_SRC emacs-lisp :results value :noweb yes
<<init_emacs>>
<<init_org>>
(org-version nil t)
#+END_SRC

#+RESULTS:
: Org mode version 9.3.6 (9.3.6-4-gdfa7a3-elpaplus @ /home/kdm/.emacs.d/DEBUG/elpa/org-plus-contrib-20200217/)

* Bug
** COMMENT Example Bug

Put example code here for this bug.

  "Measure the time it takes to evaluate BODY."
  `(let ((time (current-time)))
     ,@body
     (message "%.06f" (float-time (time-since time)))))

(measure-time (message "hello, world"))
#+END_SRC
