When working with Org Babel source code blocks, if I have a dollar sign in
my code and export it to PDF using LaTeX, it appears to parse as an
internal link. (Maybe?)
This is what it looks like:
[image: Inline image 1]
That comes from the following source code block:
#+BEGIN_SRC sql :eval no :var id=1
SELECT * FROM blah
WHERE id=$id
#+END_SRC
The resulting LaTeX from the source code block is:
\begin{minted}[]{sql}
SELECT * FROM blah
WHERE id=$id
\end{minted}
I have verified that SQL is not the only block type to do this by having a
Ruby block with nothing except a "$" in it, and got the same result.
This happens as late as commit 682bb962f3934cd50d28a9b2d0b0e0fb85746a03
with Pygments 1.6+dfsg-1ubuntu1 and the Minted included with
texlive-latex-extra 2013.20140215-2 on Linux Mint 17.2 and Emacs 24.5.1
(x86_64).
I have attached my Org Mode config (Not the actual config, but a few setqs
and a list of things that customize spits out), the test Org file, its
output, as well as the PDF generated from that.
Is this a bug? Or is there something wrong with my configuration?
Thanks.

(Still catching up on orgmode mail … sorry if you already found a way to
address the issue)

These red boxes often come from signaling a syntax error from pygments,
which I confirmed by putting the code in a test.sql file and running:
% pygmentize -f latex test.sql
\begin{Verbatim}[commandchars=\\\{\}]
\PY{k}{SELECT} \PY{o}{*} \PY{k}{FROM} \PY{n}{blah}
\PY{k}{WHERE} \PY{n}{id}\PY{o}{=}\PY{err}{\PYZdl{}}\PY{n}{id}
\end{Verbatim}
You can see the “\PY{err}” that signals a parser error around the dollar
sign.
There are some solutions to hide these boxes here:

Ah, thanks! So it was configuration then...
I initially figured it was language-dependant, which was why I tried it in
Ruby, since "$" is a valid character in that language... What I didn't
anticipate was that the boxes came from intelligent-syntax checking--I
figured that it was just some sort of fancy character I was unfamiliar with
that needed to be escaped.
So, the way I fixed the issue in my Org file was to add the following to
override the syntax error checking:
#+LATEX_HEADER: \expandafter\def\csname PY@tok@err\endcsname{}
It was recommended on that Stack Exchange answer not to do this, but we
aren't writing code directly in LaTeX, we're using Org mode..! That means
we don't really need error highlighting in our exporting, since that sort
of thing is already covered by existing language support.
