org-mode git master. ox-latex export errors out due to a table

Hi,

I updated my copy of org-mode from git master after about 2-3 weeks. The
ox-latex export used to work fine but now it is failing due to something in
the tables I have in my .org files.  If I comment out those tables, the
ox-latex export works fine. Else it errors out due to (void-function nil)
error.

Here is one of such tables. The below is a MWE which can reproduce the
error I am seeing. The error occurs when I do "C-c C-e l l"

Re: org-mode git master. ox-latex export errors out due to a table

[Nick Dokos]

Thank you for providing the backtrace, but ... You knew there was
a "but" coming, right? :-)

Although some people can make sense of a backtrace produced with
compiled code, it is far more useful to provide a backtrace produced
with *uncompiled* code. What you have to do is

C-u M-x org-reload RET

and *then* produce the backtrace. If you want to go back to compiled
code afterwards, do the M-x org-reload  without the C-u.

See

  (info "(org) Feedback")

particularly the section entitled "How to create a useful backtrace".

Also, please always provide the org-mode version:

C-u M-x org-version

FWIW, I can export your sample to PDF with no problems. I'm on
Org-mode version 8.3.2 (release_8.3.2-178-g96681f)

Apologies, I was unaware of that. I should have read that Info node first.
Below is a gist link to the full backtrace with uncompiled code.

https://gist.github.com/kaushalmodi/b76de1274b7a7bfe6020

Here's more info about this issue I am facing:
- I cannot reproduce this error in emacs -Q with the same git version of
org-mode in load-path.
- But I can reproduce this error consistently even if I "delete/move" my
~/.emacs.d/init.el and ~/.emacs.d/elpa. I do not have a ~/.emacs file.
While this step should be equivalent to emacs -Q, it doesn't seem to work
that way for me. Even the load-path var is exact same as with emacs -Q (I
install org-mode in the share/emacs dir).

While I resolve the mystery of why removing the init.el is not the same as
emacs -Q for me, I hope that the backtrace from uncompiled code can help
point the problem in my emacs setup.

Many thanks!

Also, I am on the latest org-mode and emacs builds:

Some more info:

I cannot recreate this error when using
- my emacs config
- the same emacs build from git
- BUT the latest org-plus-contrib from org elpa: Org-mode version 8.3.2
(8.3.2-10-g00dacd-elpaplus @
/home/kmodi/.emacs.d/elpa_25_0/org-plus-contrib-20151005/)

So it is some change between:
- 8.3.2-10-g00dacd-elpaplus, and
- release_8.3.2-251-g4ca117

Now I just need to decode what "g4ca117" means in that version that does
not work for me. It doesn't seem to be any part of the git hash for the
commit I am on (

@Nick Dokos Are you are on a commit before or after this lexical binding
change?
http://orgmode.org/cgit.cgi/org-mode.git/commit/?id=8bccb2131374bba8c82c2774abb34af488826ce4

The failure symtoms in my backtrace look like they could be related to this
change.

I can reproduce it with the latest version too. It may have something to
do with the recent conversion of ox-latex to lexical binding: I see
closures all over the backtrace.

My guess is that it's this commit:

commit 8bccb2131374bba8c82c2774abb34af488826ce4
Author: Nicolas Goaziou <mail@nicolasgoaziou.fr>

but I haven't reverted it yet to check.

The "g" stands for "git" and it's not part of the SHA1: 4ca117 are
the first six digits of the SHA1 at the HEAD of the branch:

Ah, now that you spell it out, it's obvious. I swear I kept staring at the
git hash to find the "117" in "g4ca117" in
http://orgmode.org/cgit.cgi/org-mode.git/commit/?id=4ca1179c9e9c707267ac3738cc7c8442001b204b
but I never saw it! Now it stands out clear.

And of course, I should have realized that "g" can never be part of the hex
hash.

Thanks, and also thanks for confirming that you see this error too.

I think that is right.

The problem seems to be with the search-refs function defined in the
let* in org-latex--delayed-footnotes-definitions and passed down to
org-element-map which tries to find it in the lexical environment and
fails.

Brute-forcing search-refs to be a special variable (i.e. dynamically,
rather than lexically, bound) seems to fix the error, although I doubt
it's the ultimate solution:
