Anybody else getting openbsc segfaults on IMSI Detach?

Hi, I pulled a newer openbsc version today for the first time in several months. Now, when a phone sends an IMSI Detach, osmo-nitb segfaults. The reason seems to be: osmo_msc.c:msc_compl_l3 gets called from gsm0408_rcvmsg, which in turn calls gsm0408_dispatch which at some point ends up in gsm48_rx_mm_imsi_detach_ind, which calls msc_release_connection, which calls gsm0808_clear, which sets conn->bts = NULL. Now, back in msc_compl_l3, trans_has_conn is called, which tries to dereference conn->bts->network, which causes the segfault. It might have been introduced with Holger's patch "msc: Attempt to release the lchan immediately on IMSI Detach" (153b13b0), but that was already in July... -Tobias
