Remember to cover the basics, that is, what you expected to happen and
what in fact did happen.

Be sure to consult the FAQ section in the manual before submitting
a bug report.  In addition check if the bug is reproducable with an
up-to-date version of AUCTeX.  So please upgrade to the version
available from http://www.gnu.org/software/auctex/ if your
installation is older than the one available from the web site.

If the bug is triggered by a specific (La)TeX file, you should try
to produce a minimal sample file showing the problem and include it
in your report.

Your report will be posted for the auctex package at the GNU bug
tracker.  Visit http://debbugs.gnu.org/cgi/pkgreport.cgi?pkg=auctex
to browse existing AUCTeX bugs.

If I do automatic line wrap in paragraphs with latex labels, e.g.,
\ref{eq:a long descriptive label}
then it will often be separated into two lines, and the reference
breaks. Same problem with labels themselves in fact.

This document

--8<---------------cut here---------------start------------->8---
\documentclass{article}
\begin{document}
\begin{equation}
  \label{eq:a very long label with spaces in it}
  a+b=c
\end{equation}
This is a very long paragraph with a~(\ref{eq:a very long label with spaces in
  it})
\end{document}
--8<---------------cut here---------------end--------------->8---

compiles fine for me, even with a line break in the ref macro.  I'd
suggest not to use spaces in labels at all, see also
https://tex.stackexchange.com/questions/149701/are-latexs-label-names-case-sensitive-can-label-names-contain-spaces#comment340547_149704

Anyway, you can add the ref macro (and all other ref-like macros) to
the `LaTeX-verbatim-macros-with-braces-local' variable in your init
file, in order to avoid breaking it:

    (add-to-list 'LaTeX-verbatim-macros-with-braces-local "ref")

Let me know if this suffices.

Bye,
Mosè
