c++filt indicates that this should demangle to:

cereal::detail::InputBindingMap<cereal::JSONInputArchive>::Serializers
cereal::polymorphic_detail::getInputBinding<cereal::JSONInputArchive>(cereal::JSONInputArchive&,
unsigned int)::{lambda(void*, std::unique_ptr<void,
cereal::detail::EmptyDeleter<void> >&)#2}*&
std::_Any_data::_M_access<cereal::detail::InputBindingMap<cereal::JSONInputArchive>::Serializers
cereal::polymorphic_detail::getInputBinding<cereal::JSONInputArchive>(cereal::JSONInputArchive&,
unsigned int)::{lambda(void*, std::unique_ptr<void,
cereal::detail::EmptyDeleter<void> >&)#2}*>()
