Mats, try updating to a version of the cc-mode package more recent than June
2005, and check if you still have the problem.
Wow, so someone else has seen this too.
I first ran into this in 21.5.20 (ref: m37jiop84i.fsf(a)uh-oh.nvidia.com)
It seemed to be triggered by lazy-lock but I couldn't figure out
why. Eventually I tracked it down enough to generate the patch
below which avoided the problem without ever figuring out what
was really happening.
The pre-idle-hook code doesn’t save-excursion, so any errors in it after the
current buffer has been changed result in the current buffer getting out of
sync. If you want to debug this sort of problem, try something like
replacing each function in pre-idle-hook with one which calls the function,
catching any error thrown, and backtracing on it.
