| Description: | When an incoming SIP call is received, asterisk crashes. This happens intermittently, sometimes often, sometimes only seldom. The crash seems to happen at or just after a specific entry in my dialplan, which is:
{noformat} exten => call-queue1,n,Log(NOTICE,${CALLID}: ---${REPLACE(REPLACE(QUEUE_MEMBER_LIST(${INCOMING_ACTION}),"Local/@phoneSIP"),",", )}---) {noformat} If the crash occurs, there is no result of the Log() in the asterisk log. I have been able to distill this to the following reproduction case: {noformat} exten => test,1,Set(TEST=Local/220@phone,1) exten => test,n,Log(NOTICE,---${REPLACE(REPLACE(TEST,"Local/@phoneSIP"),",", )}---) {noformat} Note that the original string from the queue memberships was longer: Local/220@phone,SIP/714,Local/210@phone,SIP/195. Shortening the string makes the crash go away at some point. The two dialplan lines shown above are a constant reproducer for me. | ||

By: Roel van Meer (rolek) 2014-04-23 08:29:01.927-0500 I cannot reproduce this with asterisk 11.7.0. By: Rusty Newton (rnewton) 2014-04-25 09:42:44.425-0500 Reproduced in Asterisk 12. Took about six calls to get the crash. backtrace_ast12.txt attached. By: Rusty Newton (rnewton) 2014-04-25 12:42:13.592-0500 Attaching another trace, backtrace_ast12_2.txt with accompanying mmlog.txt gathered with the MALLOC_DEBUG compiler option.
