[tex-live] Disappearing text

[Artur Zaroda]

This happens on Ubuntu 12.04 with TexLive 2009 and on Windows with
fresh installation of TexLive 2013.

For a do-it-yourself minimal working example, in the following:

\documentclass{article}
\usepackage{comment}
\includecomment{a}
\includecomment{b}
\begin{document}
\begin{a}
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
\begin{b}
\end{b}
0123456789 0123456789 0123456789 0123456789 0123456789
\end{a}
\end{document}

repeat the line with 62 '%' characters exactly 64 times.

The resulting document is shortened to:

0123456789 0123456789 0123456789 0123456789 01
