           Summary: [11/12/13 Regression] ICE: tree check: expected tree
                    that contains 'decl with visibility' structure, have
                    'field_decl' in write_unqualified_name, at
                    cp/mangle.cc:1438
           Product: gcc
           Version: 13.0

  Target Milestone: ---

gcc 13.0.1 20230122 snapshot (g:844eab81da3f49da88e8bb02e2b1255ba88d02b0) ICEs
when compiling the following testcase, extracted from
test/CodeGenCXX/mangle-nttp-anon-union.cpp from the clang 15 test suite, w/
-std=c++20:

template<typename T>
struct wrapper1 {
  union {
    struct {
      T RightName;
    };
  };
};

template<auto tparam> void dummy(){}

void uses() {
  dummy<wrapper1<double>{123.0}>();
}

% g++-13 -std=c++20 -c h6lcbgyp.cpp
h6lcbgyp.cpp: In function 'void uses()':
