ClangCodeModel module, highlight error

Good day.
Sorry for my bad English.
QtCreator 3.6.0 (downloaded from http://download.qt.io/, binary installer)
Use the library boost filesystem (1.55.0) with the Qt-creator.
Standard completion mechanism in the code editor does not work correctly with the type
boost::filesystem::recursive_directory_iterator,
so I use the code model Clang.
For this i activated the module ClangCodeModel and switch code model Clang.
Then autocompletion started working correctly, but there was another error.
Open Qt Creator options: TOOLS >> OPTIONS >> TEXT EDITOR >> COLOR SCHEME
There are options:
Primitive Type
Keyword

So after activation code model Clang,
in the code editor all the elements that belong to the group of "Primitive type" is displayed in a color that is set in the "Keyword".

Qt Creator version 3.5.1 (downloaded from http://download.qt.io/, binary installer) does not have this error.
