            Bug ID: 105787
           Summary: internal compiler error: tree check: expected
                    enumeral_type, have record_type in tsubst_copy
           Product: gcc
           Version: unknown
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: tamas+gcc@hudson-trading.com
  Target Milestone: ---

The following code causes ICE (at least) on gcc 11.2, 11.3, 12.0 and 13.0.0
20220529 (experimental) when compiling with -std=c++20:

template <typename> class a;
class b;
template <> class a<b> {
public:
  enum class c { d };
  using enum c;
};
class b : public a<b> {};
template <int> class e { char g = (char)b::d; };
e<0> f;

Full error from "13.0.0 20220529":

<source>: In instantiation of 'constexpr e<0>::e()':
<source>:10:6:   required from here
<source>:9:44: internal compiler error: tree check: expected enumeral_type,
