    MDEV-13011 Server crashes in THD::handle_condition or Assertion `! is_set() || m_can_overwrite_status' fails upon attempt to connect with max_session_mem_used = 8192

    errors when a connection is killed in the

    also, safety-wise, don't check max_mem_used on free() and when some error

    was already issued.
