In Emacs org-mode, Latex export of literal string containing “\__” giving problem

Question

I am trying to export a literal string from Emacs Org-mode to Latex for subsequent export to PDF. The literal string is:

str1\__str2

I have tried the following input in the Org file:

\verb+str1\__str2+

This produces the following code in the .tex file:

\verb+str1\hspace{3ex}str2+

I expected the following code in the .tex file:

\verb+str1\__str2+

I have also tried the following in the Org file:

\begin{verbatim}
str1\__str2
\end{verbatim}

This produces the following code in .tex file:

\begin{verbatim}
str1\hspace{3ex}str2
\end{verbatim}

Including the following option in the Org file has no effect on the output:

#+OPTIONS:     ^:{}

If you don't mind the verbatim block, which you indicated above you're ok with, then this:

#+BEGIN_EXAMPLE
   str1\__str2
#+END_EXAMPLE

Produces this:

\begin{verbatim}
str1\__str2
\end{verbatim}
