Re: [SR-Users] crash at 480 reply to INVITE

Kamailio 5.2 crashed when it received 480 reply to INVITE. Below is backtrace from the core file. The crash happens in t_reply.c on the last line of this block: uac=&t->uac[branch]; LM_DBG("org. status uas=%d, uac[%d]=%d local=%d is_invite=%d)\n", t->uas.status, branch, uac->last_received, is_local(t), is_invite(t)); last_uac_status=uac->last_received; Earlier it was checked that the transaction was found. Its uac[0] seems to be broken. -- Juha ----------------------------------------- Program terminated with signal SIGSEGV, Segmentation fault. #0_  0x00007f1073e234c3 in reply_received (p_msg=0x7f1076b605f0) at t_reply.c:2240 2240_ _ _  t_reply.c: No such file or directory.
