Summary:                    [patch] [regression] Segfault when hanging up phone
after launching app_confbridge on Solaris 10 x86
Description: 
Dead air when dialing into an app_confbridge extension. CLI output reports
playing the "conf-placeintoconf" file but you don't hear the audio. Upon
hanging up the phone Asterisk segfaults *everytime*.

*CLI>     -- Executing [3505 at default:1]
Goto("SIP/us.sip.globeop.com-00000000", "gocfb-main,s,1") in new stack
    -- Goto (gocfb-main,s,1)
    -- Executing [s at gocfb-main:1]
Answer("SIP/us.sip.globeop.com-00000000", "") in new stack
    -- Executing [s at gocfb-main:2] NoOp("SIP/us.sip.globeop.com-00000000",
""Call was answered\n"") in new stack
    -- Executing [s at gocfb-main:3]
ConfBridge("SIP/us.sip.globeop.com-00000000", "1000,aAcM,614084") in new
stack
    -- <Bridge/8555ed0-input> Playing 'conf-placeintoconf.slin16'
(language 'en')
Segmentation Fault (core dumped)


Dialplan is basic. 

context default {

        3505 => {
                goto gocfb-main|s|1;
        }
}

context gocfb-main {

        s => {

                Answer();
                NoOp("Call was answered\n");
                ConfBridge(1000,aAcM,614084);
        }
}

I just remembered something after I looked back at your backtrace, and I
believe the crash you're seeing is related to how Solaris processes
signals.  So I changed Asterisk from using signal(2) to using sigaction(2).
 This may fix the original crash that you were having.
