[pdftex] Strange error: hyperref meets multline

[Victor Ivrii]

I found a strange error (after massive usage of the construction
similar to the following)


\documentclass[12pt]{article}

\usepackage[leqno]{amsmath}
\usepackage{amssymb}


\usepackage{hyperref}


\begin{document}
\begin{equation}
1+1=2
\label{A}
\end{equation}

\newpage

\begin{multline}
2+1=2
\label{B}\tag*{$(\ref*{A})^*$}
\end{multline}

\newpage

\ref{B}

\end{document}



Document looks fine but the link on the third page which should lead
to the second one leads actually to the first.
It does not happen if I use {equation} or {align} instead of
{multline}. It also happens if I use \tag*{$(\ref{A})^*$}
It also happens if I use {mathtools} instead of {amsmath}


I use pdfTeX 3.141592-1.40.3-2.2 (Web2C 7.5.6) kpathsea version 3.5.6
latest hyperref and mathtools


Probably this is a bug

Best   Victor
