Hi,
I have got a C++ source file that causes "GNU Emacs 21.4.1"
(current Debian testing) to hang with 100% cpu. To reproduce
the bug, load the attached source file and turn font-lock-mode
on in C++ mode. If you move the cursor down, at some position,
emacs will hang and accept no more keyboard inputs.
Regards,
Dirk
