[texhax] listings causing: Command invalid in math modeCommand invalid in math mode

[Jeremy C. Reed]

I am using listings package version 1.3 as available in teTeX-texmf-3.0. 
(pkgsrc packages teTeX-texmf-3.0nb5 and teTeX-bin-3.0nb14)

My document (the final PDF) has:
11Command invalid in math modeCommand invalid in math mode

Doesn't say what command. My logging has:

I can reproduce this when I have two lstlisting blocks that define a 
custom basicstyle. So my workaround is to simply change one of them to:

\begin{lstlisting}{basicstyle=\footnotesize}
to:
\begin{lstlisting}

Here is a minimum example for me to reproduce this problem:

%%%%%%%%%%%%%%%%
%&LaTeX

\documentclass{article}

\usepackage{listings}
\lstset{
	columns=fixed
}

\begin{document}

\begin{lstlisting}{basicstyle=\footnotesize}
  A   B   C
  9   8   7
             6  5  4
             D  E  F
\end{lstlisting}

TEXT HERE

\begin{lstlisting}{basicstyle=\footnotesize}
    this is          a  test
    ofth ee          m  ergency
\end{lstlisting}

\end{document}
%%%%%%%%%%%%%%%%


I assume I am using this wrong, but I have found examples like that and 
also I thought that is what I read in the Listings package documentation.

The above generates (copy and paste from xpdf):

%%%%%%%%%%%%%%%%%%
A     B   C
9     8   7
            6   5   4
            D  E    F
  5
  TEXT HERE
  Command invalid in math modeCommand invalid in math mode
    this is           a   test
    ofth ee           m   ergency
  3
%%%%%%%%%%%%%%%%%%

I do not know where the "5" and "3" come from or the repeated error 
message. Also notice how at the "5" and later it is indented.

Any suggestions?

I don't want to set the smaller font size for all listings.

Maybe listings package is not what I need. I want simply to have verbatim 
text to be in the same font as the rest of my document while keeping a 
fixed spacing (for formatting).

Also I could accept using the default font size in the listings (no 
\footnotesize) if the fixed text in there didn't wrap.


Thank you,
