Oh! Clang is just falling back to 'int' as part of it's recovery. You aren't likely to get good results.

If you use the tooling infrastructure (http://clang.llvm.org/docs/LibTooling.html), it handles default C++ paths for you. It's far, far better than trying to construct a CompilerInstance yourself.
