[omniORB] Problem with sequences

[Cristi]

I have the following structure ('utilizator') and a sequence of elements of
this structure ('utilizatorVect')

==================================
    struct utilizator {
      CORBA::Long uID;
      CORBA::String_member cont;
      CORBA::String_member parola;
      CORBA::String_member nume;
      CORBA::String_member prenume;
      CORBA::String_member adresa;
      CORBA::String_member telefon;
      CORBA::String_member email;
      CORBA::Short activ;

      size_t NP_alignedSize(size_t initialoffset) const;
      void operator>>= (NetBufferedStream &) const;
      void operator<<= (NetBufferedStream &);
      void operator>>= (MemBufferedStream &) const;
      void operator<<= (MemBufferedStream &);
    };

    typedef _CORBA_ConstrType_Variable_Var<utilizator> utilizator_var;

    typedef _CORBA_Unbounded_Sequence<utilizator > utilizatorVect;
    typedef _CORBA_Sequence_Var<utilizatorVect, utilizator >
utilizatorVect_var;
===============================

One of the methods of the object is (it's just for trying that it works):

===================================

CORBA::Long  UserAdminLocalServer_i::ListaCompletaUtilizatori(utilizatorVect
*& utl_list) {
 utilizatorVect* temp = new utilizatorVect();
 temp->length(1);
 (*temp)[0].cont = CORBA::string_dup((const char*)"frana");
 (*temp)[0].parola = CORBA::string_dup((const char*)"aaa");
 (*temp)[0].nume = CORBA::string_dup((const char*)"frana");
 (*temp)[0].prenume = CORBA::string_dup((const char*)"ioan");
 (*temp)[0].adresa = CORBA::string_dup((const char*)"xxx");
 (*temp)[0].telefon = CORBA::string_dup((const char*)"1234");
 (*temp)[0].email = CORBA::string_dup((const char*)"frana@xxx");
 (*temp)[0].uID = (CORBA::Long)2;
 (*temp)[0].activ = (CORBA::Short)1;
 utl_list = temp;
 delete temp;
 return (CORBA::Long)1;
};

====================

And in the client:

====================
  CORBA::ORB_ptr orb = CORBA::ORB_init(argc,argv,"omniORB2");
  CORBA::BOA_ptr boa = orb->BOA_init(argc,argv,"omniORB2_BOA");

  try {
    CORBA::Object_var obj = getObjectReference(orb);
   User_Admin_Local_Server::UserAdminLocalServer_var e =
User_Admin_Local_Server::UserAdminLocalServer::_narrow(obj);

  if (CORBA::is_nil(e)) {
   return;
  }
  User_Admin_Local_Server::UserAdminLocalServer::utilizatorVect* utl_list;
  e->ListaCompletaUtilizatori(utl_list);

=======================

Could you tell me why the client crashes with a "Debug assertion failed"
(Expression: _BLOCK_TYPE_IS_VALID(pHead->nBlockUse)) when I call
