Summary0006712: Random crash on gtk_widget_queue_draw()
DescriptionAfter some UI interaction with my plugin I get SIGSEGV:

The code of the UI widget:
    void Gtk2Window::set_parent(GtkWidget *parent)
    {
        // Change size
        GtkWidget *toplevel = gtk_widget_get_toplevel(pWidget);
        if (gtk_widget_is_toplevel (toplevel) && (GTK_IS_WINDOW(toplevel)))
        {
            // Since Ardour doesn't make plugin's window always above it's window, force it to be above
            gtk_window_set_keep_above(GTK_WINDOW(toplevel), TRUE);

            // Due to having artifacts with some cairo elements on expose() we have to periodically redraw the entire window
            g_signal_connect(toplevel, "map", G_CALLBACK(map_window), gpointer(this));
            g_signal_connect(toplevel, "unmap", G_CALLBACK(unmap_window), gpointer(this));
        }
    }

    void Gtk2Window::gtk_window_set_parent(GtkWidget *widget, GtkObject *prev, gpointer p_this)
    {
        Gtk2Window *_this = reinterpret_cast<Gtk2Window *>(p_this);
        if (_this != NULL)
            _this->set_parent(widget);
    }

    gboolean Gtk2Window::redraw_window(gpointer ptr)
    {
        Gtk2Window *_this = reinterpret_cast<Gtk2Window *>(ptr);
        if ((_this != NULL) && (_this->pWidget != NULL) && (_this->bMapped))
            gtk_widget_queue_draw(_this->pWidget);
        return TRUE;
    }

    void Gtk2Window::map_window(GtkWidget *widget, gpointer ptr)
    {
        Gtk2Window *_this = reinterpret_cast<Gtk2Window *>(ptr);
        if ((_this != NULL) && (!_this->bMapped))
        {
            _this->hFunction = g_timeout_add (500, redraw_window, _this);
            _this->bMapped = true;
        }
    }

    void Gtk2Window::unmap_window(GtkWidget *widget, gpointer ptr)
    {
        Gtk2Window *_this = reinterpret_cast<Gtk2Window *>(ptr);
        if ((_this != NULL) && (_this->bMapped))
        {
            g_source_remove(_this->hFunction);
            _this->bMapped = false;
        }
    }

Okay, I began to understand what's happening.
I've added a couple of debug code, so:

    void Gtk2Window::gtk_window_set_parent(GtkWidget *widget, GtkObject *prev, gpointer p_this)
    {
        Gtk2Window *_this = reinterpret_cast<Gtk2Window *>(p_this);
        lsp_info("_this=%p, _this->pWidget=%p, _this->bMapped=%d, _this->Function=%x", _this, _this->pWidget, _this->bMapped ? 1 : 0, int(_this->hFunction));
        if (_this != NULL)
            _this->set_parent(widget);
    }

    gboolean Gtk2Window::redraw_window(gpointer ptr)
    {
        Gtk2Window *_this = reinterpret_cast<Gtk2Window *>(ptr);
        lsp_info("_this=%p, _this->pWidget=%p, _this->bMapped=%d, _this->Function=%x", _this, _this->pWidget, _this->bMapped ? 1 : 0, int(_this->hFunction));
        if ((_this != NULL) && (_this->pWidget != NULL) && (_this->bMapped))
            gtk_widget_queue_draw(_this->pWidget);
        return TRUE;
    }

    void Gtk2Window::map_window(GtkWidget *widget, gpointer ptr)
    {
        Gtk2Window *_this = reinterpret_cast<Gtk2Window *>(ptr);
        lsp_info("_this=%p, _this->pWidget=%p, _this->bMapped=%d, _this->Function=%x", _this, _this->pWidget, _this->bMapped ? 1 : 0, int(_this->hFunction));
        if ((_this != NULL) && (!_this->bMapped))
        {
            _this->hFunction = g_timeout_add (500, redraw_window, _this); // Schedule at 2 hz rate
            _this->bMapped = true;
        }
    }

    void Gtk2Window::unmap_window(GtkWidget *widget, gpointer ptr)
    {
        Gtk2Window *_this = reinterpret_cast<Gtk2Window *>(ptr);
        lsp_info("_this=%p, _this->pWidget=%p, _this->bMapped=%d, _this->Function=%x", _this, _this->pWidget, _this->bMapped ? 1 : 0, int(_this->hFunction));
        if ((_this != NULL) && (_this->bMapped))
        {
            if (_this->hFunction)
                g_source_remove(_this->hFunction);
            _this->bMapped = false;
            _this->hFunction = 0;
        }

Sorry, it's not a problem of Ardour. If Ardour re-uses plugin window, then I have to remove map and unmap handlers.

It's my inattentiveness that some signal handlers wasn't properly removed.
