Thanks, Eli. However, I still see the freezing. I have
GNU Emacs 18.104.22.168 (i486-pc-linux-gnu, GTK+ Version 3.4.2)
of 2012-08-23 on dex, modified by Debian
now, so your fix should be included.
In emacs -Q, I did C-x d ~ RET and set `cache-long-line-scans' to t.
Then I moved around in that buffer with the arrow keys and prior/ next.
After a few seconds, Emacs was frozen.
In another test, I started emacs -Q and evaluated
(setq-default cache-long-line-scans t)
Then I did some trivial things like changing current buffer and moving
around. In some cases, CPU consumption went to 100% while I did
nothing, and Emacs didn't respond anymore. Another time, Emacs aborted.
