It should be enough just to restart Emacs. So the problem is the need to restart Emacs every time after compilation. Actually, not after every compilation, but I can't determine on what condition this error depends. This is a new regression appeared in the last 2 weeks. Before some recent change, there was no need to restart Emacs after compilation.
