Re: [Sofia-sip-devel] abort()

[Colin Whittaker]

Ok, I've reproduced this now.... Looks like if I have a call in early media, 183 Session Progress, my application gets confused and sends a nua_bye() instead of nua_cancel() to end the call. Strangely enough, the stack sends the CANCEL, but then aborts. Here is some nua and nta debug: nua(0x108e4d28): signal r_bye nta: sent CANCEL (100401002) to UDP/10.0.0.233:5060 nta: received 487 Request Terminated for INVITE (100401002) nta: 487 Request Terminated going to a transaction nta: sent ACK (100401002) to UDP/10.0.0.233:5060 nta: outgoing_free(0x108d6600) nua: nua_stack_event: entering nua(0x108e4d28): r_invite 487 Request Terminated nua(0x108e4d28): call state changed: proceeding -> terminated nua: nua_stack_event: entering nua(0x108e4d28): i_state 487 Request Terminated nua: nua_stack_event: entering nua(0x108e4d28): i_terminated 487 Request Terminated nua(0x108e4d28): removing session usage nta_leg_destroy(0x108f4230) nta: received 200 OK for CANCEL (100401002) nta: 200 OK going to a transaction nta_outgoing: RTT is 124.181 ms nua: nua_stack_event: entering nua(0x108e4d28): r_bye 200 OK nua(0x108e4d28): call state changed: terminated -> terminated nua: nua_stack_event: entering nua(0x108e4d28): i_state 200 to BYE nua: nua_stack_event: entering nua(0x108e4d28): i_terminated 200 to BYE sipuad: nua_dialog.c:328: nua_dialog_usage_remove: Assertion `*at' failed.

I only found abort() in libsofia-sip-ua/su/sofia-sip/htable.h Should this really be an abort() ? What would cause this ? assert() also calls abort(), so the exit with abort() you have seen is probably caused by assert() failing elsewhere. There is no clear reason to call to abort() in htable_remove() template, the application has most probably already crashed in the previous loop.
