[reSIProcate] Maybe a bug ? SipMessage::remove() is crashed in DumFeature::process() function

[Karlsson <boost.regex@xxxxxxxxx>]

Hi all, I have write a class which derived from DumFeature, and implemented the process function:

 

 

DumFeature::ProcessingResult MyFeature::process(Message* msg)
{

 SipMessage* sipMsg = (SipMessage*)msg;
 if (sipMsg)
 {
  const resip::Data headerName("User-Agent");
  resip::Data headerValue("test);

  resip::HeaderBase * headerBase = HeaderBase::getInstance(resip::Headers::getType(headerName.c_str(),headerName.size()));

  if (headerBase)
  {
   if (sipMsg->exists(*headerBase) == true)
   {
    sipMsg->remove(*headerBase);
   }

   HeaderFieldValueList * hfvs = new HeaderFieldValueList();
   hfvs->push_back(new HeaderFieldValue(headerValue.data(), headerValue.size()));

   sipMsg->setRawHeader(hfvs, Headers::getType(headerName.data(), headerName.size()));

  }
 }

 postCommand(auto_ptr<Message>(sipMsg));

 return DumFeature::FeatureDone;
}

 

My application is crashed on sipMsg->remove(*headerBase); I have debug this function:

 

void
SipMessage::remove(const HeaderBase& headerType)
{
   delete mHeaders[headerType.getTypeNum()];   ------------------------->when runing to this line, it will be crashed.
   mHeaders[headerType.getTypeNum()] = 0;
};

 

 

Above code I have using with MessageDecorator::decorateMessage function, it's working fine.

 

And I try to use SipMessage* sipMsg = dynamic_cast<SipMessage*>(msg); to instead SipMessage* sipMsg = (SipMessage*)msg;

but it's failed, the dynamic_cast result it 0.

 

Thanks
