[asterisk-bugs] [JIRA] (ASTERISK-23650) Segfault in string functions

[Roel van Meer (JIRA)]

     [ https://issues.asterisk.org/jira/browse/ASTERISK-23650?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Roel van Meer updated ASTERISK-23650:
-------------------------------------

    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.

It occurs randomly, and attempts to find a constant reproducer have failed so far. I'll see if I can add some more details in the next few days.

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,Macro(clog,Incoming from ${CALLERID(num)} <${CALLERID(name)}> to ${EXTEN_ORG} queue 1 with members ${REPLACE(REPLACE(QUEUE_MEMBER_LIST(${INCOMING_ACTION}),"Local/@phoneSIP"),",", )})
{noformat}

The called macro at that point is:

{noformat}
[macro-clog]
exten => s,1,Set(RETURN_CONTEXT=${MACRO_CONTEXT})
exten => s,n,Log(NOTICE,${CALLID}: ${ARG1} [${MACRO_EXTEN}:${MACRO_PRIORITY} @ ${MACRO_CONTEXT}])
exten => h,1,GotoIf(${EXISTS(${RETURN_CONTEXT})}?${RETURN_CONTEXT},h,1)
exten => h,n,Hangup(16)
{noformat}

If the crash occurs, there is no result of the Log() in the asterisk log. I have not yet found the exact point of the crash, but I suspect the initial line, not the macro, because the macro works well in other places (and has done so for years), while the initial line is new.

It occurs randomly, and attempts to find a constant reproducer have failed so far. I'll see if I can add some more details in the next few days.
