Ah! The recent splitting of gnunet-service-core's "run" method into a pre-key generation and post-key generation part means that IF gnunet-service-core is shutdown prior to key generation completion, GSC_CLIENTS_done might be called even though GSC_CLIENTS_init was never invoked. In this case, client_mst is NULL. Fix is trivial. An equivalent issue also applies to GSC_SESSIONS. Both are fixed in SVN 24130. |
