With a very inelegant ECM below, I can reproduce the arithmetic range
error in emacs-26.1 but not in the development emacs-27.0.50. I have
tested the ECM on machines running Debian 3.16.0-7-686-pae and
4.9.0-8-686-pae, with the same results.
1. emacs -Q <RET>
2. We need a directory for testing. This ECM uses ~/temp.
3. In the scratch buffer, evaluate the following:
#+begin_src emacs-lisp
(add-to-list 'load-path (expand-file-name "~/path/to/git/org-mode/lisp"))
#+end_src
#+begin_src emacs-lisp
(setq org-publish-project-alist
'(("org"
:base-directory "~/temp/"
:publishing-directory "~/temp"
:publishing-function org-html-publish-to-html)))
#+end_src
4. Create file ~/temp/test.org.
5. Enter some text (e.g. This is a test) in test.org and save file.
6. M-x org-publish-current-file <RET>.
7. A satisfactory ~/temp/test.html is produced.
8. emacs-26.1 gives 'org-publish-cache-ctime-of-src: Arithmetic range error'.
9. emacs-27.0.50 gives no arithmetic range error.
10. Also no errors are produced if emacs-26.1 and emacs-27.0.50 use only
their generic org-modes, namely 'release_9.1.9-65-g5e4542'.
I hope to post a report to emacs-dev later today.
Best wishes,
