Memory leak

[vincent-richard]

I have the library connecting/disconnecting to multiple stores via IMAP in a continuous loop and every time 4 bytes are added to memory. Here is some code you can use to replicate the issue; it's nothing more than a basic connection and disconnection in a simple loop. Either this is a bug or I'm overlooking some form of destructor that the examples and documentation neglect to mention.

vmime::ref <vmime::net::store> st;
vmime::ref <vmime::net::folder> f;
vmime::platform::setHandler<vmime::platforms::posix::posixHandler>();
static vmime::ref <vmime::net::session> g_session = vmime::create <vmime::net::session>();

while(1){
    stringstream url_string;
    url_string<<"imap://blah:blah";
    cout << url_string.str() << endl;
    vmime::utility::url url(url_string.str());

    st = g_session->getStore(url);
    st->connect();
    st->disconnect();
}
