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);
        }
}

Use sigaction for signals which should persist past the initial trigger,
not signal.

If you call signal() in a Solaris signal handler, instead of just
resetting
the signal handler, it causes the signal to refire, because the signal is
not
marked as handled prior to the signal handler being called.  This
effectively
causes Solaris to immediately exceed the threadstack in recursive signal
handlers and crash.
