--- Comment #1 from Richard Smith <richard-llvm at metafoo.co.uk> ---
The behaviour you're seeing is due to C++'s two-phase name lookup. For a name
like `A` in the base specifier, unqualified name lookup is performed in the
context of the template definition, not in the context of the instantiation,
and it does not look into dependent base classes. So lookup for `A` finds the
class template ::A, not the injected-class-name, and that is not valid here.
