--- Comment #9 from Roman Zhuykov <zhroma at gcc dot gnu.org> ---
Just adding another example where I caught the same error:
$ cat test.cc
class IR;
class Pass {
public:
explicit Pass(IR *ir) : ir_(ir) {}
virtual ~Pass() = default;
IR *ir_ {nullptr};
};
class PassManager {
public:
template <typename T> void RunPass() { T pass(ir_); }
IR *ir_ {nullptr};
};
class IR final {
public:
template <typename T> void RunPass() { pass_manager_.RunPass<T>(); }
PassManager pass_manager_;
};
class ThePass : Pass {
public:
explicit ThePass(IR *ir) : Pass(ir) {}
ThePass(const ThePass &) = delete;
template <typename Func = bool (*)(void *)> void Bar(void *inst, Func func
= [](void *) {});
};
void foo(IR *ir) { ir->RunPass<ThePass>(); }
$ g++ -fchecking -g -c test.cc # any g++ from 8 to 13
test.cc:18:7: error: type variant has different ‘TYPE_FIELDS’
