           Product: gcc
           Version: 11.0
            Status: UNCONFIRMED

Hi, all.

This code, reduced by C-Vise, makes GCC-trunk ICE and makes released GCC
versions "confused by early errors".

Input:
//small.cc
enum struct a : struct {};
template <class b> enum class a : class c{};
enum struct a {b};

Command:
g++ small.cc

Output:
small.cc:1:25: error: underlying type ‘<unnamed struct>’ of ‘a’ must be an
integral type
    1 | enum struct a : struct {};
      |                         ^
small.cc:3:13: error: different underlying type in enum ‘enum class a’
    3 | enum struct a {b};
      |             ^
small.cc:1:25: note: previous definition here
    1 | enum struct a : struct {};
      |                         ^
small.cc:3:16: internal compiler error: tree check: expected integer_type or
enumeral_type or boolean_type or real_type or fixed_point_type, have
record_type in int_fits_type_p, at tree.c:8954
    3 | enum struct a {b};
