 Reftex occasionally mixes up the levels of sectioning in the toc

[Message part 1 (text/plain, inline)]

Hello,

Sometimes (rarely), reftex-toc cannot place some sections at their
correct level.

The following document is more or less minimal:

"""
\documentclass{report}
\begin{document}

\chapter{Chapter 1}
\subsection{Subsection 1}
\section*{Section}
\section{Section 2}

\end{document}

%%% Local Variables:
%%% mode: latex
%%% TeX-master: t
%%% End:
"""

The table of contents presented by reftex-toc is the following:

"""
   1 Chapter 1
       1.0.1 Subsection 1
         * Section
     1.1 Section 2
"""

Notice how the unnumbered section is ranked deeper than the subsection.

Removing the subsection, the chapter, or changing the unnumbered section
for a numbered
one all make the abnormal behavior disappear.

Promoting and demoting works as expected, but anything down from chapter
(so, anything but
part) is shifted a few indents to the right. A chapter* would be aligned
with the
subsection, and subdivisions are indented further.

The bug also happens with `emacs -Q`.
