Using shared_ptr's in `unrecognized_entity_exception` can lead to cross-cpu deletion of a pointer which will trigger an assert `_cpu == std::this_thread::get_id()' when shared_ptr is disposed. Copy `column_identifier` to the exception object and avoid using an instance of `cql3::relation`: just get a string representation from it since nothing more is used in associated exception handling code.
