Hello,

  I updated my version of Emacs from CVS recently, and this problem
still occurs.

  I also have a simplified reproduction step.  Start with this C++
file:

----------
/* A comment */
/*
 * A multi-line comment
 */
-----------

Make sure font lock has fontified this entire buffer.

Mark the entirety of the multi-line comment, and use C-w to kill the
region.  Font lock will throw an error and stop auto-updating.

You can also use C-k on the last line in this buffer, to get the same
effect.

Thanks
Eric
