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
