Hi, I updated pjsip to the last svn version. I compiled them on iphone and I tried my app and ipjsua. In both cases app crashes (login or first call). I believe this issue comes when app receives a message. It seems this issue arrive with compilation option -Os and not with -O0. #0 0x351fcf38 in memmove () #1 0x0002032c in pj_memcpy (dst=<value temporarily unavailable, due to optimizations>, src=<value temporarily unavailable, due to optimizations>, size=<value temporarily unavailable, due to optimizations>) at string.h:634 #2 0x00020724 in pj_strdup (pool=<value temporarily unavailable, due to optimizations>, dst=0x849c38, src=0x7cc9724) at string_i.h:41 #3 0x0005bdf0 in pjsip_generic_array_hdr_clone (pool=0x8d8400, rhs=0x7cc9700) at ../src/pjsip/sip_msg.c:937 #4 0x00074954 in pjsip_dlg_set_remote_cap_hdr (dlg=0x8d8464, cap_hdr=0x7cc9700) at ../src/pjsip/sip_dialog.c:2159 #5 0x00074adc in pjsip_dlg_update_remote_cap (dlg=0x8d8464, msg=0x8d4d8c, strict=-1) at ../src/pjsip/sip_dialog.c:2071 #6 0x000766a8 in pjsip_dlg_on_rx_response (dlg=0x8d8464, rdata=0x8d3c14) at ../src/pjsip/sip_dialog.c:1786 #7 0x000785b8 in mod_ua_on_rx_response (rdata=0x8d3c14) at ../src/pjsip/sip_ua_layer.c:892 #8 0x0007073c in tsx_set_state (tsx=0x90ac64, state=PJSIP_TSX_STATE_PROCEEDING, event_src_type=PJSIP_EVENT_RX_MSG, event_src=0x8d3c14) at ../src/pjsip/sip_transaction.c:1138 #9 0x00071cc0 in tsx_on_state_proceeding_uac (tsx=0x90ac64, event=0x7cc9904) at ../src/pjsip/sip_transaction.c:2841 #10 0x00071f1c in pjsip_tsx_recv_msg (tsx=0x90ac64, rdata=0x8d3c14) at ../src/pjsip/sip_transaction.c:1690 #11 0x00072d48 in mod_tsx_layer_on_rx_response (rdata=0x8d3c14) at ../src/pjsip/sip_transaction.c:852 #12 0x00064d68 in endpt_on_rx_msg (endpt=0x88c064, status=<value temporarily unavailable, due to optimizations>, rdata=0x8d3c14) at ../src/pjsip/sip_endpoint.c:927 #13 0x00069dd8 in pjsip_tpmgr_receive_packet (mgr=0x852a54, rdata=0x8d3c14) at ../src/pjsip/sip_transport.c:1510 #14 0x0006abdc in udp_on_read_complete (key=0x88cd18, op_key=<value temporarily unavailable, due to optimizations>, bytes_read=454) at ../src/pjsip/sip_transport_udp.c:171 #15 0x00016b98 in ioqueue_dispatch_read_event (ioqueue=0x88c730, h=0x88cd18) at ioqueue_common_abs.c:559 #16 0x000171e8 in pj_ioqueue_poll (ioqueue=0x88c730, timeout=<value temporarily unavailable, due to optimizations>) at ../src/pj/ioqueue_select.c:902 #17 0x000646d4 in pjsip_endpt_handle_events2 (endpt=0x88c064, max_timeout=0x7cc9f98, p_count=0x7cc9fa0) at ../src/pjsip/sip_endpoint.c:719 #18 0x000959b0 in pjsua_handle_events (msec_timeout=<value temporarily unavailable, due to optimizations>) at ../src/pjsua-lib/pjsua_core.c:1506 #19 0x000971b4 in worker_thread (arg=<value temporarily unavailable, due to optimizations>) at ../src/pjsua-lib/pjsua_core.c:567 #20 0x0001850c in thread_main (param=<value temporarily unavailable, due to optimizations>) at ../src/pj/os_core_unix.c:492 #21 0x3527598c in _pthread_start () #22 0x3526b0ec in thread_start () any ideas ?
