Package varwidth Warning: “Failed to reprocess entire contents” if hyperref is loaded

[dbitouze]

The following MCE:

\documentclass{article}
\usepackage{varwidth}
% \usepackage{hyperref}
\begin{document}
\begin{varwidth}[t]{.5\linewidth}
\section{A Section}\label{sec:section}
Cf. section \ref{sec:section}.
\end{varwidth}
\end{document}

is okay but, as soon as hyperref is loaded, it triggers (twice) the following warning:

Package varwidth Warning: Failed to reprocess entire contents on input line 8.

well varwidth doesn't like the bookmark command. You can add some support for it, but generally I would avoid to do to much in a varwidth ...

\documentclass{article}
\usepackage{varwidth,etoolbox}
\usepackage{hyperref}
\makeatletter
\let\@@vwid@addcontentsline\addcontentsline 
\def\@vwid@addcontentsline#1#2#3{\@vwid@wrap{\@@vwid@addcontentsline{#1}{#2}{#3}}}
\preto\@vwid@setup{\let\addcontentsline\@vwid@addcontentsline}
\makeatother
\begin{document}
\begin{varwidth}[t]{.5\linewidth}
\section{blub}
x
\end{varwidth}
\end{document}

I agree with you about direct use, but my real use case is actually based on the standalone package which is based on varwidth. And, AFAICS, standalone is widely used.

[u-fischer]

standalone is clearly used too much. It is fine for a picture but I don't see the use for a document with a section and hyperref links.

My use case is a math article in an “endless” page.
