Hi,

We are using globaldefs::NamingAttributes_T_var to access the notifications from CORBA (TAO+ACE).

<code>
if (strcmp(notification.filterable_data[i].name,"objectName") == 0)
{
globaldefs::NamingAttributes_T_var testStruct;

if (notification.filterable_data[i].value >>= testStruct) {

for (CORBA::ULong j=0; j < testStruct->length() ; j++ )
{
cout<<"struct of name"<<(*testStruct)[j].name<<endl;
cout<<"struct of value"<<(*testStruct)[j].value<<endl;

}
}
}
<code end>

While executing the above, getting segmentation fault from #0 0x00000019 in ?? ()
#1 0x080824b4 in globaldefs::NVSList_T::_tao_any_destructor(void*) ()

Can you please suggest, is it necessary to free the testStruct? We tried using "testStruct->release()" and free(testStruct). But getting the same error again. Please suggest.
