c++-mode: Invalid function: (setq ad-return-value (ad-Orig-c-parse-state))

I can't insert important C++ characters into my code (attached). When I
press ; or { Emacs shows an error in the minibuffer:

"Invalid function: (setq ad-return-value (ad-Orig-c-parse-state))"

Major mode is c++-mode.

Using Emacs 24.2.1.

because Emacs kept complaining

"Invalid function: (setq ad-return-value (ad-Orig-c-parse-state))"

more like a screwup in your setup. ad-Orig-c-parse-state suggests you
have advised c-parse-state.

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.  ;-)

I have not used advise myself, but maybe one of the packages I am using has.

My .emacs:

My crystal ball says you have some advice somewhere which has
"(ad-do-it)" instead of "ad-do-it".
