[pstricks] It is probably a bug in psVector with showpoints

[Donut E. Knot]

Dear folks,

I just want to let you know the following. It may be a bug.

Activating showpoints produces a compile error in PostScript phase.

\documentclass[pstricks,border=12pt]{standalone}
\usepackage{pstricks-add}
\psset{showpoints}% <--- source of error!
\begin{document}
\begin{pspicture}[showgrid](-5,-5)(5,5) 
    \psset{linecolor=blue}
    \psline(1,0)  
    \pstVerb{/Angle 0 def}
    \psStartPoint(1,0)% <--- why is it needed? 
    \multido{\i=1+1}{15}
    {% <--- why is it needed?
\pstVerb{Angle 1 \i\space 1 sub sqrt atan add  /Angle exch def }
\psVector[arrows=-](! 1 Angle PtoC)
        \psline(! cp.X cp.Y)
    }
\end{pspicture}
\end{document}

Thank you.

Code Mocker
