I have seen one issue myself, so maybe that's also it. To verify: Can you 
please do the following:

In one of the erroneous files, open the Problems tool view, select "show 
imports" and then inspect the errors that you see? 

In my case, I've sometimes seen issues with the maximum template instantiation 
depth being reached, leading to dozens of errors which eventually let the 
parser give up. Is that the case for you too? Can you fix it by increasing the 
instantiation depth via the project settings -> custom defines/includes -> 
compilers -> add -ftemplate-depth=1024 or even something higher?
