[reSIProcate] Crash with TCP transport and malformed messages


Hi,

I am seeing the following crash (Windows XP Service Pack 2, Visual Studio
.NET 2003, server is SER 0.9, user agent is based on resip 0.9):

>     reSIPAgent.dll!resip::AppDialogSet::getHandle()  Line 21 + 0x3    C++
      reSIPAgent.dll!resip::DialogUsage::getAppDialogSet()  Line 38 + 0x18
C++

reSIPAgent.dll!ClientHandler::onUpdateActive(resip::Handle<resip::ClientSubscription>
 handle={...}, const resip::SipMessage & notify={...})  Line 477  C++
      reSIPAgent.dll!resip::ClientSubscription::dispatch(const
resip::SipMessage & msg={...})  Line 140  C++
      reSIPAgent.dll!resip::Dialog::dispatch(const resip::SipMessage &
msg={...})  Line 426    C++
      reSIPAgent.dll!resip::DialogSet::dispatch(const resip::SipMessage &
msg={...})  Line 645    C++
      reSIPAgent.dll!resip::DialogUsageManager::processRequest(const
resip::SipMessage & request={...})  Line 1286   C++

reSIPAgent.dll!resip::DialogUsageManager::internalProcess(std::auto_ptr<resip::Message>
 msg={...})  Line 909   C++
      reSIPAgent.dll!resip::DialogUsageManager::process()  Line 1044 + 0x49
C++

In ClientHandler::onUpdateActive, I have:

void ClientHandler::onUpdateActive(ClientSubscriptionHandle handle, const
SipMessage& notify)
{
      ClientAppDialogSet *pSet = NULL;
 >>   AppDialogSetHandle hDialogSet = handle->getAppDialogSet();

In:

AppDialogSetHandle
DialogUsage::getAppDialogSet()
{
   return mDialog.mDialogSet.mAppDialogSet->getHandle();
}

The mAppDialogSet member is NULL.

This happens a few minutes after the user agent REGISTERed with the TCP
transport. The crash occured with the last NOTIFY in the trace below. Also,
in the trace below, some SUBSCRIBE messages were malformed. I don't see the
problem when using UDP with the same server, the same sequence of presence
subscriptions, etc.

Has anyone seen this?
