           Product: clang
           Version: unspecified
          Hardware: PC
                OS: All
            Status: NEW

I wonder if this fallthrough is intentional?

  case Type::Auto:
  case Type::DeducedTemplateSpecialization:
                               OnlyDeduced, Depth, Used);

  // None of these types have any template parameters in them.
  case Type::Builtin:
  case Type::VariableArray:
  case Type::FunctionNoProto:
  case Type::Record:
  case Type::Enum:
  case Type::ObjCInterface:
  case Type::ObjCObject:
  case Type::ObjCObjectPointer:
  case Type::UnresolvedUsing:
  case Type::Pipe:
#define TYPE(Class, Base)
#define ABSTRACT_TYPE(Class, Base)
#define DEPENDENT_TYPE(Class, Base)
#define NON_CANONICAL_TYPE(Class, Base) case Type::Class:
#include "clang/AST/TypeNodes.def"
