Bug report

Bug description:

Pointer left is dereferenced here, but null-pointer check is done later. Correct code should look like this:

    int result;
    if (left == NULL || right == NULL) {
        PyErr_BadInternalCall();
        return NULL;
    }

    PyTypeObject *sesstype = ((PySSLSession*)left)->ctx->state->PySSLSession_Type;
