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

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.
------------------------------------------------------------------------

When the file is a .tex file, I can use C-c ; to comment and uncomment
the \begin{equation} environment.

Once the file is a Noweb version (extension .rnw), if I use C-c ; to
comment or uncomment this environment it crashes emacs completely.

I've tried other environments such as itemize or figure and these work
fine.

Any thoughts?

Minimal Example:

==========================

\documentclass{article}



\begin{document}

\begin{equation}
  \label{eq:hxvol2}
  \begin{aligned}
    Vol &= & n\ \times L\ \times\ \frac{\pi D^2}{4}\\
  \end{aligned}
\end{equation}

\end{document}

Let me understand the recipe to reproduce the problem.  You save that
file as a noweb file (that is, with *.rnw extension) and when you
issue C-c ; Emacs crashes?  AUCTeX doesn't fiddle with Emacs
internals, it shouldn't make Emacs crash.  I noticed you're running a
development version of Emacs, did you try with a stable one?  I tried
with Emacs 24.5.1 and nothing happened (apart from commenting the
code).

I started with a complete reinstall of Emacs 24.5.1 (including deleting and reinstalling the Auctex, Org and Magit packages) and the same issue occurred.  For more clarification, I can initially comment the equation section, but when I go to uncomment, I get the hourglass.

If you like, I can do a video for you.

Ok, now I can reproduce it with Emacs 24.5.1 as well when I uncomment
a region (but not when I comment it).  I'll try to dig into it.  Thank
you!

No, there is no need anymore.

BTW, it's not a real crash (that would be a more serious problem), it
looks like like an infinite loop, but I'm still working to find the
culprit.

Usually (at least in my book) a crash means that the programs stops
working and exits, here instead you can recover Emacs by pressing C-g
one or more times.  This is usually the indication that a function
entered an infinite loop (or something similar) that you can break
with C-g.

Actually, yes.  I'm using version 16.04.  I'll try the prior version of 15.09 and see what happens.

Hi Shawn,

I wasn't able to find the source of the problem, I only discovered
that the function that halts is `uncomment-region-default', but when I
`edebug' it the problem goes away.

I reported the bug to ESS project:
https://github.com/emacs-ess/ESS/issues/354  I hope they can help us.

It seems that you encountered a Heisenbug.

If so, edebug is probably not the best choice.

Yes, I know, indeed I linked the same Wikipedia article in the ESS bug
ticket ;-)

Ok, but how to debug then?  I noticed that if I press C-g repeatedly
only the first line is uncommented, the others remain commented, so
the infinite loop must lies somewhere between the first and the second
deletion of the comment string, but I can't discover where exactly.

Bye,
Mosè

Dear all,

this bug should have been fixed in ESS:
https://github.com/emacs-ess/ESS/issues/354

Bye,
