Possible CLANG issue in Creator

Fairly frequent intermittent issue

Repro case

1. Start a new project (in my case a gui app)
2. Create a new class (in my case, Verifier) that inherits QObject
3. Add the Q_DECLARE_METATYPE(Verifier) after the class declaration in the header file.
4. Switch to the main.cpp source file.
5. #include "verifier.h"
6. In the main function, add qRegisterMetaType<Verifier>("Verifier");

Expected result:

The CLANG model shows no errors and the application compiles.

Actual result:

The CLANG model shows an error and the message is something like "expected ;" The application compiles, but the error still shows in the editor. To get rid of it, restart Creator.
