In Parser::ParseUsingDeclaration(...) when we call ParseEnumSpecifier(...) it is not calling SetTypeSpecError() on DS when it detects an error. That means that DS is left set to TST_unspecified. When we then pass DS into Sema::ActOnUsingEnumDeclaration(...) we hit an llvm_unreachable(...) since it expects it to be one of three states TST_error, TST_enum or TST_typename.
