Ah.  That's worrying.  The cause of the slowdown will not be found in
that single line of code, rather in its context.

The way CC Mode works is, at each buffer change, a region around the
change where side effects might propagate is calculated.  This region is
then checked for any such side effects.  I'm guessing here, but it might
well be that the region in this case has been extended far more than is
necessary.

Is there any way you could get a copy of the file to me, specifying a
line which shows the problem?  It's practically impossible to debug
otherwise.

Thanks!
