Bug 695992

This is a follow up to:
Bug 695162 - Internal hyperlinks lost when converting to pdf
http://bugs.ghostscript.com/show_bug.cgi?id=695162

I first compile Ulrike's example using dvips.exe then gswin64.exe:
\documentclass{book}
\usepackage{hyperref}
\begin{document}
\chapter{Titre}
lala\ref{chp:deux}
\chapter{Titre}\label{chp:deux}
\end{document}

Links work if I don't specify a pdf password in the ghostscript options:
-sDEVICE=pdfwrite -dBATCH -dNOPAUSE -sOutputFile="%bm.pdf" "%bm.ps"

but links don't work if I specify a password:
-sDEVICE=pdfwrite -dBATCH -dNOPAUSE -sUserPassword=pass -sOwnerPassword=pass  -sOutputFile="%bm.pdf" "%bm.ps"

I'm using Ghostscript 9.15 for Windows (64 bit)
