Contains a copy of a project with the bug and a screenshot.

In some header files the code completion goes haywire and marks nearly all of the identifiers with the "unable to resolve identifier X" error. This happened in a C++11 Application project.

I tried to replicate the bug with minimal code, but I wasn't able, so I attached my project and a screenshot in a zip file.
In this project the error first appeared in Screen.hpp. Then after some time it started to work again, but the error reappeared in the previously working Error.hpp (see the screenshot).
Regardless of this, the project compiles without any warning or error.

The project has external dependencies on SFML 2.1 and pugixml, but I hope the bug shows itself without them too.

I don't know what triggers this bug or any workarounds for it, but I find this bug a mayor showstopper for NetBeans 7.4.

Thanks to Petr for investigation it's regression caused by

Comment 2 Vladimir Voskresensky 2013-09-29 14:48:47 UTC 
if header file guarded by pragma once has conditional preproc blocks like
#if ...
#else
...
#endif

then code assistance in such files is completely broken
