[Bug-AUCTeX] 11.81; longlines-mode -> hang

[David Reitter]

When I load a reasonably sized tex file (795 lines, 10800 words)
(mode line says: PDFLaTeX/F Fly BCite Ref Abbrev) and turn on  
longlines-mode, the whole Emacs hangs for about a minute or so.

The same happens when I'm in longlines-mode and turn it off while  
displaying a buffer in latex-mode.

I can reproduce that with a different tex file, too.

When I set "Soft Word Wrap in Text modes", i.e. when longlines-mode  
is turned on per default, and then a file in latex-mode is loaded, I  
don't get that problem. longlines works fine and the system doesn't  
hang - loading the file is instantaneous.

I don't  know whether this is due to auctex or to longlines - I'm  
sure you'll know. Let me know if you need more information.




Be sure to consult the FAQ section in the manual before submitting
a bug report.  If the bug (or problem) 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 bug report will be posted to the AUCTeX bug reporting list.
