I'm using version: libcurl-7.16.4-win32-ssl-sspi

http://localhost/test.csv - test.csv contains plain-text and is about
500Kb big. It doesn't matter which kind of content I'm receiving.

Two examples which are both leaking:
EXAMPLE 1: This example obviously doesn't hold the connection. I wanted
to get closer to the problem, but the memory is still growing.

bool abc::test()
{
    ::AfxBeginThread(test_worker, this);
    return true;
}
UINT abc::test_worker(LPVOID pParam)
{
    Communicator* pDlg = (abc*) pParam;
    int i=1;

    while(true)
    {
        Communicator *con1 = new Communicator();

        TRACE("abfrage %i\r\n",i);
        i++;

        CString quellcode;
        con1->communicate("http://localhost/test.csv","",quellcode,"");

        con1->_delete();
        delete con1;
    }

    return true;
}

EXAMPLE 2: con1 is a global instance of my class

bool abc::test()
{
    ::AfxBeginThread(test_worker, this);
    return true;
}
UINT abc::test_worker(LPVOID pParam)
{
    Communicator* pDlg = (abc*) pParam;
    int i=1;

    while(true)
    {
        TRACE("abfrage %i\r\n",i);
        i++;

        CString quellcode;
        con1->communicate("http://localhost/test.csv","",quellcode,"");
    }

    return true;
}

This problem has a much lower priority. I would like to fix the memory
size problem first.

Thank you,
