Ice::Application within an IceUtil::Tthread

I want to run Ice::Application within an IceUtil::Thread.
I get an exception when exiting the application.

I have included the MSVC7.1 project
Also if you break just before Thread::run exits you will see that the second argument of argv has been zeroed. Bug?

I realise that it is not the most effecient thread usage.

The reasoning is the fastest way to add Ice to an existing app.

Thanks

Alfred

    Running this under the debugger, you'll see that the problem is caused by main terminating while your thread is still running, causing memory corruption. You need to use a ThreadPtr variable to hold a reference to the thread, and join with your thread before main() returns.

    Thank you for the prompt response.

    The corruption is already there as the IceUtil::Thread::run() method is entered.

    Look at argv[1] it is zeroed!!!!!

    Sorry the corruption should be Ice::Application::run() method

    im refering to the argv of Thrd::run().

    that is the corruption happen somewhere between the
    app.main(1, argv, "Ice.config"); call and
    the Ice::Application::run() method being entered.


    There is not much I can do as this is all Ice code.

    Or have I not set something up properly?

    Have a look at this:

    app.main(1, argv, "Ice.config");

    You are telling main that argv has only one element, not two elements.
    It should be:

    app.main(2, argv, "Ice.config");

    By the way, the C++ standard requires argv to be terminated with a null pointer, so you really should define your dummy argv as:

    char*argv[] = { "test1", "test2", 0 };

    That's because code that parses argv is free to ignore the value of argc and to just loop over the argument vector looking for the terminating null pointer.

    Cheers,

    Michi.
