set_client_option_2d() built the temporary key string with the connection's persistent flag but always released it with persistent=1. On a duplicate-key update of the connect_attr hash, zend_hash_update() does not retain the passed key, so the caller-owned non-persistent string was freed via free() instead of efree(), tripping the IS_STR_PERSISTENT assertion in debug builds and mismatching allocators in release. Reachable by retrying mysqli_real_connect() on a handle whose first connect failed, since mysqlnd re-adds _client_name and _server_host on every connect attempt.
