Hello,

I have a problem exporting code chunks to LaTeX (beamer, in fact -- but that
does not change anything to the problem) that contain underscores.

For example, the following:

--8<---------------cut here---------------start------------->8---
* Rule language
*** E.g.
#+BEGIN_lstlisting
months_employed(?applicant, ?months) AND
lessThan(?months, 3) AND
assets(?applicant, ?assets) AND
lessThan(?assets, 10000.0)
-> RejectedApplicant(?applicant)
#+END_lstlisting
--8<---------------cut here---------------end--------------->8---

generates:

--8<---------------cut here---------------start------------->8---
\begin{frame}[fragile]
\frametitle{Rule language}
\begin{itemize}
\label{sec-1}

\item{E.g.}
\label{sec-1.1}

\begin{lstlisting}
months$_{\mathrm{employed}}$(?applicant, ?months) AND
lessThan(?months, 3) AND
assets(?applicant, ?assets) AND
lessThan(?assets, 10000.0)
-> RejectedApplicant(?applicant)
\end{lstlisting}


\end{itemize}
\end{frame}
--8<---------------cut here---------------end--------------->8---

and, if I escape the underscore, such as:

--8<---------------cut here---------------start------------->8---
* Rule language
*** E.g.
#+BEGIN_lstlisting
months\_employed(?applicant, ?months) AND
lessThan(?months, 3) AND
assets(?applicant, ?assets) AND
lessThan(?assets, 10000.0)
-> RejectedApplicant(?applicant)
#+END_lstlisting
--8<---------------cut here---------------end--------------->8---

the exporter generates:

--8<---------------cut here---------------start------------->8---
\begin{frame}[fragile]
\frametitle{Rule language}
\begin{itemize}
\label{sec-1}

\item{E.g.}
\label{sec-1.1}

\begin{lstlisting}
months\_employed(?applicant, ?months) AND
lessThan(?months, 3) AND
assets(?applicant, ?assets) AND
lessThan(?assets, 10000.0)
-> RejectedApplicant(?applicant)
\end{lstlisting}


\end{itemize}
\end{frame}
--8<---------------cut here---------------end--------------->8---

So, I can't get a properly outputted underscore in my slide.

Any idea or workaround?

Best regards,
  Seb
