Your problem is that you keep updating the master copy of your list in
the screen controls until it is NULL - at which point the list is
empty and the contents leaked.

Instead, try something like this (I didn't test it):

void SendMessage(GtkWidget * button, screen_controls * sc)

{
    int i = 0;
    GList *list;

    list = g_slist_nth ( sc->group, i );

    while ( list != NULL && i < 3)

    {
        if (GTK_TOGGLE_BUTTON (list->data)->active == TRUE)

        {
            cout << i << endl;
         }

        list = g_slist_next ( list );

        i++;
    }
}
