--- Comment #7 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Reduced testcase:
struct __new_allocator {};
template <typename> using __allocator_base =3D __new_allocator;
struct allocator : __allocator_base<int> {};
template <class> struct initializer_list {
  void *_M_array;
  decltype(sizeof 0) __rebind;
};
struct basic_string {
  basic_string(const char *, allocator =3D allocator());
  ~basic_string();
};
struct array {
  basic_string _M_elems;
};
struct list {
  void operator=3D(initializer_list<array>);
};
}
struct RGWSyncTraceManager {
  std::list admin_commands;
  void hook_to_admin_command();
};
void RGWSyncTraceManager::hook_to_admin_command() {
  admin_commands =3D {{""}, {""}};
