[reSIProcate] bug in StatelessHandler::process() ?

[martin.van.den.berg at philips.com]

The stateless proxy has probably undergone some bit rot. Can you run your
test and post the output with the log level set at Log::Stack.

e.g.

./stateless-proxy -l cout -v STACK  ...
<..........>




Ok, you can find the trace below:

I've made a little change in StatelessHandler.cxx which makes it work. But 
I don't know if this is 100% correct...

            else  // line 59
            {
               DebugLog (<< "Processing request from TU : " << 
msg->brief());
               StatelessMessage* stateless = new StatelessMessage(mController.mTransportSelector, sip);
               DnsResult*dnsr = 
mController.mTransportSelector.dnsResolve(sip, stateless);
                // Modification MvdB 2004-08-02: Added 5 lines
                   if (dnsr->available() == DnsResult::Available )
                   {
                          mController.mTransportSelector.transmit(sip, 
dnsr->next() );
                   }
                   delete dnsr;
                // End Mod
            }
