[reSIProcate] What's going on?

[John Draper <lists@xxxxxxxxxxxxxxxx>]

Hi,

Below is a description of the problem I'm having with issuing an Invite 
command
to our SIP server.  The partial code fragment explains the problem.

ClientInviteSession::dispatchStart (const SipMessage& msg)
{
 assert(msg.isResponse());
 assert(msg.header(h_StatusLine).statusCode() > 100);
 assert(msg.header(h_CSeq).method() == INVITE);

 InviteSessionHandler* handler = mDum.mInviteSessionHandler;
 std::auto_ptr<SdpContents> sdp = InviteSession::getSdp(msg);

 InviteSession::Event event = toEvent(msg, sdp.get());
 switch (event)
 {
    case On1xx:
       transition(UAC_Early);
       handler->onNewSession(getHandle(), None, msg);    <--- Here is 
where it calls my InviteHandler.
       if(!isTerminated())         {
          handleProvisional(msg);
       }
       break;

-----------------------------------------------------------------
My Invite handler's "onNewSession" handler

void
InviteClient::onNewSession(ClientInviteSessionHandle, 
InviteSession::OfferAnswerType oat, const SipMessage& msg)
{
  cout << ": ClientInviteSession-onNewSession - " << msg.brief() << endl;
    // gets the status line of this message,  should be 200 OK.
  // but this is how you get it if you need it.
  int code = msg.header(h_StatusLine).statusCode();  
  // save the data coming in.
  // registerHandle = h;
  reqresponse = msg;              <--- I break just before calling 
this,  then "Step over",  and get following..
    [mBridge status:@"Inv: Attempting to connect"];
}

<--------  RESULT --------->

Since the "=" is an override...  I eventually get here....  Not 
surprisingly.

SipMessage&
SipMessage::operator=(const SipMessage& rhs)
{
 if (this != &rhs)
 {
    this->cleanUp();      <---- and here is where things get interesting.

Does this mean the code is trying to delete the object on the LEFT side of
the "=" if they happen to be different?   In this case,
------------------------------------

void
SipMessage::cleanUp()
{
 for (int i = 0; i < Headers::MAX_HEADERS; i++)
 {
    delete mHeaders[i];   <---- Crashes here with  i=0
    mHeaders[i] = 0;
 }

-----------
Am I to assume, the problem is in the statement....

reqresponse = msg;

Since "=" is overridden,  according to the code I see above,  why would 
it try to
first delete reqresponse?

Is that intentional, or am I mis-using the resip stack?   If I am,  I 
can certainly
believe it, since no such document describes what I'm to do....

By the way,  in my "onNewSession" handler,  I'm getting back a 180 AFTER 
first
getting a 200 OK.   Is this what it's supposed to do?
