bug#24079: 11.89.4; Auctex noweb issue.

[Shawn Way]

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.

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).

Bye,
