[reSIProcate] Getting a DestroyUsage...

Hi,
I'm crashing in the following code in DialogUsageManager.cxx line 935
Partial code listed below from lines 931 - 937 - this is in the DumThread
code and "DialogUsageManager::internalProcess" gets called repeatedly
getting the response data back from SIP server. One such request data
is a
DestroyUsage response. What exactly is a DestroyUsage object, it's
purpose in life, and why would I get one coming back to me after issuing
an Invite?
DestroyUsage* destroyUsage = dynamic_cast<DestroyUsage*>(msg.get());
if (destroyUsage)
{
DebugLog(<< "Destroying usage" << *destroyUsage);
destroyUsage->destroy(); <----- Crashes here....
return;
}
DestroyUsage::destroy()
{
if (mDialogSet)
{
delete mDialogSet; <---- Crashes here.
}
else if (mDialog)
{
delete mDialog;
}
else if (mHandle.isValid())
{
delete mHandle.get();
}
}
And why would I want to delete my dialogSet after issuing an Invite? Is
this a normal
thing it's supposed to do? I presume so, but in chasing down the
problem, it eventually
gets to here...
HeaderFieldValueList::~HeaderFieldValueList()
{
for (iterator i = begin(); i != end(); i++) <---- Last thing it
was pointing to before crashing
{
delete *i;
}
delete mParserContainer;
}

Program received signal: "EXC_BAD_ACCESS".
I presume this is normal for the stack to destroy the
"usageDestroyDialogSet"?
I'm not getting any of the "InviteSessionHandler", or "OutOfDialogHandler"
callbacks at all at this stage.
But the Sip server is getting the Invite request and is processing the
200 OK I'm getting
back from the server. One other thing I notice, is that I'm getting
more then one
200 OK coming back. Why is this? Is this normal? I'm sure the answer
it hidden in
one of the 275 pages of the RFC, but help me out please.... I'm sure
I'm just not
constructing the INvite message properly.... Message and "sdp" I'm
using is listed below,
am I forgetting something?

===================================================
There are some things I'm not doing, but should, but I doubt if it has
anything to do with why I'm getting the above behaviour.
I'm not specifying the Codec count.... Do you think that if I don't
specify it, that could be causing the crash? Because the crash
happens when destroying the message, and if that isn't setup,
then the interator may have the wrong count.
