This is a known problem which has been fixed (by removing an
"improvement") in the soon-to-be-released Emacs 23.2. The "improvement"
itself has been fixed for the medium future Emacs 24.
The bug is triggered by inserting a newline at the end of any C
preprocessor line. This wrongly pushes a "CPP marker" (actually a text
property) onto the start of the next line.

Upgrade to Emacs 23.2 when it gets released. This could be as early as
the coming Friday.
Sorry for this bug.
