[O] Unexpected macro error

[Thomas S. Dye]

Aloha all,

A document I've been working on for several weeks broke recently without
changes on my part. However, I've been tracking the master git branch
every once in a while and I suspect some change in Org is the culprit.

Org-mode version 8.3beta (release_8.3beta-580-g787733 @ 
/Users/dk/.emacs.d/src/org-mode/lisp/)

I haven't tried to make an ECM because I don't know what the problem
could be.  Here is a backtrace:

Debugger entered--Lisp error: (error "Undefined Org macro: ad; aborting.")
  signal(error ("Undefined Org macro: ad; aborting."))
  error("Undefined Org macro: %s; aborting." "ad")
  org-macro-replace-all((("author" . #("Thomas S. Dye" 0 13 (:parent (#("Thomas 
S. Dye" 0 13 (:parent #4)))))) ("date" . "\\today") ("email" . 
"address@hidden") ("title" . #("Dating human dispersal in Remote Oceania: A 
view from Hawai`i" 0 61 (:parent (#("Dating human dispersal in Remote Oceania: 
A view from Hawai`i" 0 61 (:parent #4))))))) finalize)
  org-export-as(latex nil nil nil (:output-file "./dispersals.tex"))
  org-export-to-file(latex "./dispersals.tex" nil nil nil nil nil #[(file) 
"\301!\207" [file org-latex-compile] 2])
  org-latex-export-to-pdf(nil nil nil nil)
  (org-open-file (org-latex-export-to-pdf nil s v b))
  (if a (org-latex-export-to-pdf t s v b) (org-open-file 
(org-latex-export-to-pdf nil s v b)))
  (lambda (a s v b) (if a (org-latex-export-to-pdf t s v b) (org-open-file 
(org-latex-export-to-pdf nil s v b))))(nil nil nil nil)
  org-export-dispatch(nil)
  call-interactively(org-export-dispatch nil nil)
  command-execute(org-export-dispatch)

The error message refers to a macro, ad.  I don't have an "ad" macro.
Where does this come from?

The next header line, after the headers that become macros, is
#+ADDRESS:, which starts with "ad", although the case is different.

Also, the string "ad" occurs frequently in my writing as the path in a
custom link that sets the path as small caps in LaTeX output,
e.g. [[sc:ad][AD]].

You can see that I'm groping in the dark.  Any suggestions how I might
go about debugging this?

All the best,
Tom
