I found the app_swift module (that I've been helping maintain) makes
asterisk crash on versions higher than 11.19.0 - something that happened
on 11.20.0-rc1 makes asterisk segfault. I realize app_swift is not a
'supported' module -- I'm just having a hard time finding the cause and
am wondering if I could borrow anyone's eyes.

of note, app_swift doesnt /always/ crash asterisk, e.g., when I call
into asterisk from a phone and swift is in the dialplan, all seems fine.
it seems that it's just when I make a callfile that dials out.


a backtrace is at http://pastebin.com/Dfd4P8sK

replication is easy (if you have swift):
echo "testing 1 2 3" > /var/lib/asterisk/tts
cat <<__EOE__ >> /etc/asterisk/extensions.conf
[intercom]
exten => _2XZ,1,SIPAddHeader(Alert-Info: Ring Answer)
exten => _2XZ,n,Page(SIP/${EXTEN},diqA(local/intercom))
[tts]
exten => s,1,Wait(1)
exten => s,n,GotoIf($[0${LEN(${TEXT})} > 1]?text)
exten => s,n,Set(SPEECH=${SHELL(cat /var/lib/asterisk/tts)})
exten => s,n,Goto(swift)
exten => s,n(text),Set(SPEECH=${TEXT})
exten => s,n,NoOp(${SPEECH})
exten => s,n(swift),Swift(${SPEECH})
exten => s,n,Hangup
__EOE__

cat <<__EOS__ > /var/spool/asterisk/tmp/test123
Channel: Local/221@intercom
Callerid: "TTS" <0>
MaxRetries: 2
WaitTime: 45
Context: tts

__EOS__

mv /var/spool/asterisk/tmp/test123 /var/spool/asterisk/outgoing/test123

Not sure if I can provide much help, however I have had problems with
Swift segmentation faults in the past. The problems I had were related
to the license server causing an Asterisk segmentation fault any time
security scans hit the server. That was with Asterisk 11.8. Cepstral has
been unable to fix this issue and I'm considering using Nuance in the
future. They did provide a workaround but that created an object leak,
which forces a nightly restart of Asterisk.

Program terminated with signal 11, Segmentation fault.
#0 0x00007fb08dd02061 in LM_set_port_number () from
/opt/swift/lib/libswift.so.6
#0 0x00007fb08dd02061 in LM_set_port_number () from
/opt/swift/lib/libswift.so.6

I'd be interested to see if anyone has any ideas on your issue though.
