XEmacs throws a wrong-type-argument exception from org-export-as-pdf
if org file contains '&'. See sample document, traceback, and patch
below.
This may well not be the best fix. And it's not clear why this issue
doesn't exist in Emacs. But there are several regular expressions in
org-export-latex-special-chars that call
org-export-latex-treat-backslash-char with a nil value for
string-after. The regular expression that matched "MB&A" is
"\\(.\\|^\\)\\(&\\)". So there is no (match-string 3).
Here's a document that generates the exception:
--8<---------------cut here---------------start------------->8---
* Header
MB&A
* Footer
--8<---------------cut here---------------end--------------->8---
Here's the traceback:
