Problem with verbatim-environment

[egraff]

Check if using \begin{verbatim}\end{verbatim} causes any problems...

my one instance of verbatim is fine, but it's outside of the running text. what are we looking for?

@transmetro: I just observed that @Jaklin got errors from the tikz package when trying to use a verbatim-environment (for some reason), but I haven't had time to look into it (or see if it's even reproducible...)

I was finally able to reproduce the bug.

MNWE:

\documentclass{uit-thesis}
\usepackage{lipsum}
\begin{document}

\mainmatter

\section{A section}
\lipsum[1-4]

\begin{verbatim}
A
B
C
D
E
\end{verbatim}

\end{document}

It seems that the bug is only present with the newest version of the tikz package (or some other package). The problem is that if a verbatim environment crosses a page boundary where the running head of the first(!) page contains a UiT slash (drawn with tikz), then tikz halts with the following error message:

Sorry, some package has redefined the meaning of the math-mode dollar sign.
This is incompatible with tikz and its calc library and might cause unrecoverable errors.

A more generic MNWE:

\documentclass{book}
\usepackage{tikz}
\usepackage{lipsum}

\begin{document}

\def\testcatcode{%
  \ifnum\catcode`\$=3%
  \else
    \GenericError{}{Dollar catcode has changed}{}{}
  \fi
}%

\newcommand{\printrheadslash}[1][]{
  \testcatcode
  \typeout{^^J Before ^^J^^J}
  \begin{tikzpicture}
    \fill[color=black] (0,0) -- (1.15,3.15) -- (1.4,3.15) -- (0.25,0) -- cycle;
  \end{tikzpicture}
  \typeout{^^J After ^^J^^J}
}

\renewcommand{\sectionmark}[1]{\markboth{}{\printrheadslash}}

\section{A section}
\lipsum[1-4]

\begin{verbatim}
A
B
C
D
E
F
G
H
\end{verbatim}

\end{document}
