Dear all,
I have, until now, used a macro
#+macro title The title of the document
to be subsequently used in the actual #+title line, as in
#+title: @@latex:...@@ {{{title}}} @@latex:...@@
(LaTeX details not important, I think.)
but this now leads to a recursive evaluation of the line when exporting,
causing an infinite loop.
Changing the name of the macro to something else avoids the issue. I'm
not entirely sure why a macro expansion of the #+title line would be
recursive but there you are!

just out of curiosity, I tried to reproduce this error but it works
fine here. Do you still have this error?
Thanks,

Yes. The following minimal example does not export with my
configuration.
#+begin_src org
,#+macro: title The actual title
,#+title: @@latex:\fbox{@@ {{{title}}} @@latex:}@@
,#+options: toc:nil num:nil
,* heading
And some text follows.
#+end_src
I have not tried with emacs -Q. I will do so if this example works fine
for you.
Thanks,
eric

Hi Eric,
thanks for the time you took for an example.

Yes it works both with my configuration and with emacs -Q here, with
GNU Emacs 27.0.50 (build 51, i686-pc-linux-gnu) and Org mode version
9.1.8.

Interesting. So obviously something in my configuration. Sigh. I may
be gone some time :-)
Thanks for checking,

Very strange. Just tried with emacs -Q, org up to date from git, and it
still doesn't work for me. Actual contents of file are:
#+begin_src org
,#+macro: title This is the actual title
,#+title: @@latex:\fbox{@@ {{{title}}} @@latex:}@@
,* heading
this is some text.
#+end_src
The backtrace, after waiting a little bit, is:
--8<---------------cut here---------------start------------->8---

I am not surprised that there is an infinite loop given that title is
being replaced by something that includes the title macro? Or am I
misreading the backtrace?
Interestingly, although I have updated org and the log says that 8 hours
ago you created the 9.1.8 release, the org version is still 9.1.6.
In any case, no worries as simply changing the macro name (& subsequent
use) to titlecontents or similar does the job.
thanks,
eric

I hate to suggest this, but could there be something wrong in your
installation?

Well, even if the workaround works, I think we should prevent Org from
crashing here.
I will try to test after you confirm it does not work with Org>9.1.6.
Thanks!

Hi Bastien,
don't hesitate at all to suggest this! There's always that
possibility. :-( I don't think I have a mixed installation although I'm
not sure how to verify this.
Now, the really interesting thing is that if I use emacs -Q and try
exporting the file with the version of org that comes with the latest
emacs snapshot,
GNU Emacs 27.0.50 (build 1, x86_64-pc-linux-gnu, GTK+ Version 3.22.29) of 2018-03-18, unofficial emacs-snapshot build: http://emacs.secretsauce.net
Org mode version 9.1.6 (release_9.1.6-50-g96b33f @ /usr/share/emacs/27.0.50/lisp/org/)
the export works!
If I emacs -Q and make sure the load path points to the git version of
org, it doesn't work. When I do so, I have
Org mode version 9.1.6 (release_9.1.6-341-g3a4fd3 @ /home/ucecesf/git/org-mode/lisp/)
and git status says:
--8<---------------cut here---------------start------------->8---
On branch master
Your branch is up to date with 'origin/master'.
nothing to commit, working tree clean
--8<---------------cut here---------------end--------------->8---
I do not understand why the org version is not 9.1.8. What does your
say?

Indeed, but I am stuck as to how to proceed. Suggestions welcome, of
course!
Thanks,
eric

Org is probably getting loaded before you tweak the load paths. e.g. emacs
-Q foo.org would do that. That version looks like the one that's on
emacs-26/master branch of Emacs.
I had written a post to fix such issues and be able to specifically use Org
(1) that ships with Emacs (2) from Elpa, or (3) from git.
Sorry if you have already read it and this sounds like spam:

I can reproduce the freeze on master. I will have a look at it whenever
I get some spare time, i.e., hopefully this night.

Thank you. What is the number after the 9.1.6- in the org version for
yours? I do not load the file immediately. My means of testing is:
emacs -Q
evaluate
#+begin_src emacs-lisp
(add-to-list 'load-path "~/git/org-mode/lisp")
(require 'org)
#+end_src
and then visit foo.org to test.
I get a different version of org (differing in the number of 9.1.6-) if
I evaluate that lisp code when compared to not evaluating it.
Thanks again,
eric

Indeed, thanks for fixing this! Let's all increase our confidence in
our sanity, that something we strongly need when debugging Emacs :)
