The non-atomic data object m_peer_ids is shared between both ConnectionSendThread and ConnectionReceiveThread. It is copied in all instances without a lock. This crash is probably caused by ConnectionSendThread modifying m_peer_ids at the same time ConnectionReceiveThread is reading it and it is copied in an inconsistent state. Should be fixed with #2980
