Hoping someone can help debug this. I'm getting a seg fault (OS X 10.4) whenever the dialplan hits an expression with brackets in it. This happens on a fresh install, latest trunk, no modifications to config files. Here's what the console output looks like if you make the first item of the dialplan include a bracket: 2007-12-25 17:33:59 [DEBUG] sofia_glue.c:1447 sofia_glue_negotiate_sdp () Set 2833 dtmf payload to 101 2007-12-25 17:33:59 [DEBUG] sofia.c:1444 sofia_handle_sip_i_state() sofia/default/1000@192.168.1.4:5060 State Change CS_NEW -> CS_INIT 2007-12-25 17:33:59 [DEBUG] switch_core_session.c:633 switch_core_session_signal_state_change() Kill sofia/default/ 1000@192.168.1.4:5060 [BREAK] 2007-12-25 17:33:59 [DEBUG] switch_core_state_machine.c:402 switch_core_session_run() sofia/default/1000@192.168.1.4:5060 Running State Change CS_INIT 2007-12-25 17:33:59 [DEBUG] switch_core_state_machine.c:414 switch_core_session_run() (sofia/default/1000@192.168.1.4:5060) State INIT 2007-12-25 17:33:59 [DEBUG] mod_sofia.c:87 sofia_on_init() sofia/ default/1000@192.168.1.4:5060 SOFIA INIT 2007-12-25 17:33:59 [DEBUG] mod_sofia.c:100 sofia_on_init() sofia/ default/1000@192.168.1.4:5060 State Change CS_INIT -> CS_RING 2007-12-25 17:33:59 [DEBUG] switch_core_session.c:633 switch_core_session_signal_state_change() Kill sofia/default/ 1000@192.168.1.4:5060 [BREAK] 2007-12-25 17:33:59 [DEBUG] switch_core_state_machine.c:402 switch_core_session_run() sofia/default/1000@192.168.1.4:5060 Running State Change CS_RING 2007-12-25 17:33:59 [DEBUG] switch_core_state_machine.c:417 switch_core_session_run() (sofia/default/1000@192.168.1.4:5060) State RING 2007-12-25 17:33:59 [DEBUG] mod_sofia.c:117 sofia_on_ring() sofia/ default/1000@192.168.1.4:5060 SOFIA RING 2007-12-25 17:33:59 [DEBUG] switch_core_state_machine.c:64 switch_core_standard_on_ring() Standard RING sofia/default/ 1000@192.168.1.4:5060 2007-12-25 17:33:59 [INFO] mod_dialplan_xml.c:217 dialplan_hunt() Processing test->20! 2007-12-25 17:33:59 [DEBUG] mod_dialplan_xml.c:106 parse_exten() test conditions ${numbering_plan}() =~ /^[0-9]$/ Here's what I get from gdb on the core file: #0 0x00000000 in _mh_dylib_header () No symbol table info available.
