[texhax] fancyvrb UseVerbatim numbered lines bug

[José Romildo Malaquias]

Hi.

I want to typeset some text verbatim with numbered lines using the
fancyvrb package. In the situation the issue has arisen I need to use
SaveVerbatim and UseVerbatim. Here is a test program:

   \documentclass[a4paper]{article}
   \usepackage{fancyvrb}

   \begin{document}

   \begin{SaveVerbatim}{TestVerb}
     \textcolor{blue}{this} is verbatim
     input using the \emph{Verbatim} environment
     from the fancyvrb package
     ok
   \end{SaveVerbatim}

   \UseVerbatim[frame=single,numbers=left]{TestVerb}

   \end{document}

In the typeset document all lines in the verbatim are labeled with the
number 4, instead of 1, 2, 3 and 4.

Is this a known issue with the fancyvrb package? Any hints on how to get
verbatim numbered lines with UseVerbatim?

Regards,

Romildo
