Yup.  Reported it a few days ago, but it wasn't possible to reproduce
it.  What is the common denominator here?  I'm using Debian sid and
rebuilt Emacs freshly with make distclean + ./configure + make
bootstrap.

This thread mentioned font-lock too and I'm seeing weird font-lock
behaviour in C-mode too.  Unless it is fixed by fixing the above
problem (which I suspect), I can do a proper bug report.
