[cfe-dev] CXCursor_CXXBaseSpecifier for template instantiated base class

[Jusufadis Bakamovic via cfe-dev]

You should be getting three times the `CXCursor_CXXBaseSpecifier`, one for
each class you're inheriting from. I ran the analysis on my machine (clang
3.8) and that is exactly what I am getting: `RecursiveBase<class Base>`,
`Base2`, `Base3`. Maybe you could use `clang -Xclang -ast-dump
-fsyntax-only <this_demo>` to see the output of Clang's built-in AST
dumper. It should contain these entries. Otherwise, clang version you're
running might be an older one.
