Attached zip file with project. There are two markers in code(Tut.cpp):
ERR1, ERR2.
ERR1: many incorrect completion variants(it dumps constants, headers etc
from many places - it results in 58KB file).
ERR2: error on completion(error 2 from my first message).
Unfortunately to reproduce ERR1 you should have Ogre installed.
ERR2 should be possible to reproduce on project code.

I also tried another simple project setup with vector class from stl.
Completion variants were correct there.
That leads me to beleive that some defines from Ogre(like OGRE_PLATFORM,
_OgreExport, _OgrePrivate) break semantic.

So to summarize:
*What works:*
Ogre::Real - completes fine
Ogre::SOME_CONST - completes fine
function name or variable name from local buffer - completes fine

*What does not work:*
*1)*
void TutorialApplication::configureTerrainDefaults(Ogre::Light* light)
{
  light-> //a lot of garbage variants
}

*2)*
mRoot is defined in BaseApp.h and its type is visible in echo area.
But when trying to complete mRoot's member function in Tut.cpp I get error
(error "Cannot find types for `\"mRoot\"'").
I think semantic cannot derive its type. It can understand types of local
variables only(and mRoot is defined in another file).

*3)*
In function main local variable is defined TutorialApplication app.
When trying to complete
app.
I always get
(wrong-type-argument semantic-find-tags-by-scope-protection parent
semantic-tag-class type)

*4)
*When trying to complete*
*this->
I always get
(wrong-type-argument semantic-find-tags-by-scope-protection parent
semantic-tag-class type)
