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":

--- Comment #2 from Richard Biener <rguenth at gcc dot gnu.org> ---
But it's not a regression since it always ICEd when the feature required was
implemented. GCC 10 rejects the code:
t.ii:6:9: error: expected nested-name-specifier before 'enum'
6 | using enum c;
| ^~~~
t.ii:9:44: error: 'd' is not a member of 'b'
9 | template <int> class e { char g = (char)b::d; };
| ^
