[tao-users] CORBA::ORB_init leaks memory?

[Patryk Małek]

Hello,

I have a system using ace+tao (2.1.5. + 6.1.5) and I have a problem with
CORBA::ORB_init that leaks memory. valgrind stacktrace:

orb is of type CORBA::ORB_var;

​InterfaceThread.cpp:598  orb = CORBA::ORB_init(argc, argv);​

then in InterafceThread destructor I release it:

    if (CORBA::is_nil(orb.in()) == false) {
        orb->shutdown(1);
        orb->destroy();
        CORBA::release(orb);
        orb = CORBA::ORB::_nil();
    }

​I do not know what is the problem here. Can anyone help me here? I have
tried to dig in forums but I encounter 14 year old threads :)​
