[omniORB] SEGV on Red Hat Enterprise Linux AS release 3 in servant_to_reference

[radamkie at kdm.pl]

Hello,

I have problem with Segmentation fault by migration omniORB application
from SunOS Sparc platform to Linux ix86 platform. On the first everything goes
allright. I use there omniORB4.0.3. By migration on Linux platform I tested
the same application with omniORB4.0.3 but also with omniORB4.1.0. In 
both cases I receive Segmentation fault error in this place (marked by 
***)

CORBA::Object_var  obj;
orb = CORBA::ORB_init(argc, argv, "omniORB4");
obj = orb->resolve_initial_references("RootPOA");
poa = PortableServer::POA::_narrow(obj);
PortableServer::POAManager_var  pman = poa->the_POAManager();
pman->activate();
..
FILE *file = fopen(NameServiceIORFileName,"r")
...
fread(buffer, sizeof (unsigned char), BUFFER_SIZE, file);
...
obj = orb->string_to_object(buffer);
...
root = CosNaming::NamingContext::_narrow(obj);
...
PortableServer::ObjectId_var  obj_id = poa->activate_object(servant);
...
/***/ CORBA::Object_var  ref = poa->servant_to_reference(servant);
...
--------------------------------------------------

No core file.


Deeper analize show that problem is by line marked below by "***" in 
..../src/lib/omniORB/orbcore/poa.cc file in function 
servant_to_reference()


CORBA::Object_ptr
omniOrbPOA::servant_to_reference(PortableServer::Servant p_servant)
{
....

if( !pd_policy.multiple_id ) {
    // Search the servants identities, to see if it is
    // activated in this poa.

    omnivector<omniObjTableEntry*>::const_iterator i, last;
    i    = p_servant->_activations().begin();
    last = p_servant->_activations().end();

    for (; i != last; i++) {
/***/      if ((*i)->adapter() == this) {
        omniObjTableEntry* entry = *i;

        OMNIORB_ASSERT(pd_poaIdSize == 0 ||
                       omni::ptrStrMatch(pd_poaId, (const char*)entry->key()));

        omniObjRef* objref =
          omni::createLocalObjRef(p_servant->_mostDerivedRepoId(),
                                  CORBA::Object::_PD_repoId, entry);
        OMNIORB_ASSERT(objref);
        return (CORBA::Object_ptr) objref->_ptrToObjRef(CORBA::Object
                                                        ::_PD_repoId);
      }
    }
  }

Can anybody help , how to resolve the problem with Segmentation fault?
