Hello I'm able to reproduce a crash when combining Asterisk 13.10.0 with PJSIP 2.5.5. The crash seems to be related to Changeset 5373 as I'm not able to reproduce it when reversing this changeset. Backtrace: #0 0x00007f20d18b4ce8 in pjsip_auth_clt_deinit () from /usr/lib/libpjsip.so.2 #1 0x00007f20d18ba93e in destroy_dialog () from /usr/lib/libpjsip.so.2 #2 0x00007f20d18bb20f in pjsip_dlg_create_uac () from /usr/lib/libpjsip.so.2 #3 0x00007f20c2bd1fd6 in ast_sip_create_dialog_uac () from /usr/lib/asterisk/modules/res_pjsip.so #4 0x00007f20be4bfc4b in ast_sip_session_create_outgoing () from /usr/lib/asterisk/modules/res_pjsip_session.so #5 0x00007f20bbc5cecc in ??
