[reSIProcate] Exception can not be catched by a try/catch block

[Murat BAYKIZ]

Hi all,

Resiprocate sip stack terminates(core dump occurs) while processing a sip message. When I analyzed the core, I see there is something wrong with the transaction-id.  At SipMessage.cxx line 334 - An exception is thrown and although main has a try/catch block the exception is not catched. 

const Data& 
314	SipMessage::getTransactionId() const
315	{
316	   if (empty(h_Vias))
317	   {
318	      InfoLog (<< "Bad message with no Vias: " << *this);
319	      throw Exception("No Via in message", __FILE__,__LINE__);
320	   }
321	   
322	   assert(exists(h_Vias) && !header(h_Vias).empty());
323	   if( exists(h_Vias) && header(h_Vias).front().exists(p_branch) 
324	       && header(h_Vias).front().param(p_branch).hasMagicCookie() 
325	       && (!header(h_Vias).front().param(p_branch).getTransactionId().empty())
326	     )
327	   {
328	      return header(h_Vias).front().param(p_branch).getTransactionId();
329	   }
330	   else
331	   {
332	      if (mRFC2543TransactionId.empty())
333	      {
334	         compute2543TransactionHash();
335	      }
336	      return mRFC2543TransactionId;
337	   }
338	}

I also add a try/catch around the line 334, but the exception still was not catched and the program terminated.

332	      if (mRFC2543TransactionId.empty())
333	      {
              try{
334	         compute2543TransactionHash();
              }catch(...){
                 // can not catch the exception
              }
335	      }

We are working on Solaris 10 with gcc 4.3.3. 
Any idea about the problem?

Thanks,
Murat
