Like Leo suggested, it looks like somebody's put a `defadvice' on
c-parse-state, though I've no idea why that should produce an "Invalid
function" error.  The code for advice has changed somewhat between Emacs
24.2 and 24.3.

Can you say why c-parse-state was advised?  Possibly for debugging?  In
that context, I would strongly advise you upgrade your Emacs to 24.3.  In
Emacs 24.2, c-parse-state was buggy, and now it is, well, less buggy.  ;-)
