C faute de segmentation en essayant de résoudre une référence CORBA

Question

Quand im essayant de résoudre une référence CORBA Je reçois une erreur de segmentation. Soit aveugle im ou je l'ai fait quelque chose de vraiment stupide pour ce travail pas. Im en utilisant ACE 5.7.9 TAO 1.7.9 pour CORBA. Vous vous demandez si quelqu'un peut me aider plaît ???

Le défaut de segmentation semble se produire sur la ligne "serverRef = Corba :: Orb :: getOrb () resolveObjectReference (myIOR.c_str ());". comme commentant cette ligne entraînera l'application à exécuter bien.

J'ai copié tout le code dependan ci-dessous.

bool ClsSend::ServerObject::resolveServerRef()
{
  clssendlog << debug << "In ClsSend::ServerObject::resolveServerRef 1" << endl;
 bool referenceIsUsable = true;
 ostringstream errMsg;

 // Are we dealing with a new reference?
 if (CORBA::is_nil (serverRef.in()))
 {
   try {
     Monitor crit (mutexCoreRef);

     if (CORBA::is_nil (serverRef.in()))
     {
       // Step 1: Resolve the object reference
       serverRef = Corba::Orb::getOrb().resolveObjectReference <GenericServerWithTransport> (myIOR.c_str());

       // Step 2: Ping to check connectivity if reference is not null
       if (!CORBA::is_nil (serverRef.in()))
         serverRef->ping();
       else
       {
         errMsg << "Not registered in naming server.";
         referenceIsUsable = false;
       }
     }
   } catch (const CORBA::COMM_FAILURE &exc) {
     errMsg << "CORBA::COMM_FAILURE";
     referenceIsUsable = false;
     setRefNil();
   } catch (const NamingException &exc) {
     errMsg << exc;
     referenceIsUsable = false;
     setRefNil();
   } catch (...) {
     errMsg << "Unknown exception";
     referenceIsUsable = false;
     setRefNil();
   }
 }
 return referenceIsUsable;

}

Dang, qui est beaucoup de code dans une question ...

Mon regard suivant dans un cas comme celui-ci serait de diviser cette ligne offenser:

serverRef = Corba::Orb::getOrb().resolveObjectReference (myIOR.c_str());

en autant de parties que possible, et essayer de voir quelle partie se plante. Après cela, essayez de voir ce qui est mal à cela une partie.
