Why this code doesn't work?

[codekiddy <codekiddy gmail com>]

Simple example:

#include <pangomm/layout.h>

#include <gtkmm/window.h>

int main(int argc, char* argv[])

{

Glib::RefPtr<Gtk::Application> app = Gtk::Application::create( argc, argv, "gtkmm.exe" );

class TestClass :

public Gtk::Window

{

public:

TestClass()

{

layout = (create_pango_layout("blah"));

}

Glib::RefPtr<Pango::Layout> layout;

};

TestClass instance;

return app->run(instance);

}

program builds and runs fine, but when closing the app down, it throws in Layout::~Layout() destructor. Access violation reading location.

Can you reproduce this?
