            Bug ID: 37768
           Summary: expected the class name after '~' to name a destructor
           Product: clang
           Version: 6.0
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: C++11
          Assignee: unassignedclangbugs at nondot.org

I want to inherit the ctors of the base class and have a user-defined dtor in
my template specialization Class<Enum::b>. This won't work because I used a
type alias to name the base class, then I used the real class name to name the
inherited ctor. After this the name of the dtor doesn't get recognized anymore.

enum class Enum{
    a, b, c

template<Enum, typename...>
struct Class {};

template<typename... Args>
using base_t = Class<Enum::a, Args...>;

template<typename... Args>
struct Class<Enum::b, Args...> : base_t<Args...>{
    using base_t<Args...>::Class;
    ~Class() {} // expected class name after '~' to name a destructor

int main() {}
