Export of this table fails LuaLaTeX compilation

[gerard . vermeulen]

Hello,

I am regularly updating 9.6-pre from https://elpa.gnu.org/devel/ and 
yesterday
my LaTeX export stopped working.  The org-mode snippet below (attached, 
together
with the LaTeX export file) shows the problem.  The LaTeX file compiles 
after I remove
all occurrences of \relax.

#+title: Export of this table fails LuaLaTeX compilation
#+macro: nit (eval (format "@@latex:\\colorbox{red}{\\texttt{%s}}@@" 
$1))
#+options: title:nil toc:nil
Macro {{{nit(works outside table)}}} but fails inside tables where
=\\= matters. The LaTeX export fails to compile with LuaLaTeX because
of =\\\relax= instead of =\\=:
|-----------------------------------------|
| @@latex:\colorbox{red}{\texttt{bug}}@@  |
| {{{nit(bug)}}}                          |

exports to:
#+begin_src latex :exports none :results silent
  \begin{center}
  \begin{tabular}{l}
  \hline
  \colorbox{red}{\texttt{bug}}\\\relax
  \colorbox{red}{\texttt{bug}}\\\relax
  \hline
  \end{tabular}
  \end{center}
