Drawing a closed smooth line using TikZ, with cycle option

Question

I need to draw a couple of lines in TikZ and some of those lines need to be closed. But My code compiles in one machine but gives an error in the other, and the only difference is the version of LaTeX.

MWE

\documentclass{article}
\usepackage{tikz}
\begin{document}
    \begin{tikzpicture}
        \draw (0,0) to[out=90,in=135]
              (0,1) to[out=315,in=120]
              (1,1) to[out=315,in=270]
              (0,0);
        %\draw (0,0) to[out=90,in=135]
        %      (0,1) to[out=315,in=120]
        %      (1,1) to[out=315,in=270]
        %      cycle;
    \end{tikzpicture}
\end{document}

That version works on both computers, however, if I comment the first \draw and uncomment the second, I get an error in the computer with the older version of texlive.

Runaway argument?
\tikz@@to@collect cycle; \end {tikzpicture}
! Paragraph ended before \tikz@collect@coordinate@onpath was complete.

I cannot upgrade that machine (work computer), so I'm leaving out the cycle option, using the explicit coordinate instead, for compatibility reasons. I'm just wondering if anybody knows what's the cause of this behaviour?

BTW, the cycle option works fine for straight lines

\draw (0,0) -- (0,1) -- (1,1) cycle;

EDIT: in the not-updated system, using \pgfversion in the document prints 2.10, the version of the PGF package. And calling \listfiles in the preamble prints in the log

Answer 1

Based on the comments, I checked the Changelog documentation of the pgf package, and saw many changes after the version I was using, including the following

2013-06-18 Till Tantau <[email protected]>

    - Fixed bug #236 "Scaled closed paths, start/end points dont exactly match":
      "cycle" can now be used with all path operations where it
      makes sense, not only with --. In particular, things like
      ".. cycle" or "to [bend right] cycle" are now allowed.

Hence, I'm just seeing an old bug in an old version of the package.

Thanks!
