Re: [sr-dev] segfault with t_suspend() / t_continue()

I got the following coredump while doing some testing with t_suspend() and t_continue() on the first INVITE: (gdb) bt #0  qm_detach_free (qm=0x7fe2dae65000, size=16) at mem/q_malloc.c:269 #1  qm_malloc (qm=0x7fe2dae65000, size=16) at mem/q_malloc.c:386 #2  0x00007fe2e5e6d541 in update_totag_set (t=0x7fe2db0f42d0, ok=<value optimized out>) at t_reply.c:372 #3  0x00007fe2e5e72387 in relay_reply (t=<value optimized out>, p_msg=<value optimized out>, branch=2, msg_status=200, cancel_data=0x7fff63fdf9b0, do_put_on_wait=1) at t_reply.c:1854 #4  0x00007fe2e5e733e6 in reply_received (p_msg=0x7fe2e6a55ba0) at t_reply.c:2370 #5  0x00000000004547f5 in do_forward_reply (msg=0x7fe2e6a55ba0, mode=<value optimized out>) at forward.c:799 #6  0x000000000049a5ba in receive_msg (buf=<value optimized out>, len=961, rcv_info=0x7fff63fdfc40) at receive.c:270 #7  0x00000000005281a6 in udp_rcv_loop () at udp_server.c:544 #8  0x0000000000464d3a in main_loop () at main.c:1638 #9  0x0000000000467a6c in main (argc=<value optimized out>, argv=<value optimized out>) at main.c:2566 I suspend the transaction in one route and then I continue it in another route, similar to below: route[INVITE] # Suspend and put to memcache: t_suspend();         xlog("proceesing suspended in transaction [$T(id_index):$T(id_label)]\n");         $var(transaction_index)=$T(id_index);         $var(transaction_label)=$T(id_label);                  $mct(wait_$tU)= "" + $var(transaction_index) + ":" + $var(transaction_label);         $mctex(wait_$tU) = 100; } route[INVITE_resume]  { # get the transaction index and lable from memcache      $avp(check) = $mct(wait_$tU) ; # I should have the transaction index and the transaction label here      $var(my_transaction_index) =  $(avp(check){s.select,0,:});     $var(my_transaction_label) =  $(avp(check){s.select,1,:});     $var(a)= $(var(my_transaction_index){s.int});     $var(b) = $(var(my_transaction_label){s.int});     t_continue( "$var(a)",  "$var(b)" , "my_relay_route"); }   route[INVITE_resume] executes only on an asynchronous event (a certain SIP message that might come or not) .  I use kamailio 4.0.0/Centos Linux. I suspect it happened when I sent CANCEL, but I could not reproduce. I still have the core file. Regards, Dragos _______________________________________________
