    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 :)​

    Hi,

    Probably you are not releasing all CORBA references or made an error
    with the usage of var/ptr/duplicate. When you run the TAO/tests/Hello
    test you should see no valgrind leaks (at least it doesn't do with the
    latest micro). Try to just do a CORBA::init and a shutdown, that should
    be leak free.

    Johnny
