[osg-users] how to use StateSetManipulator in mfc?

[forest37]

 hi all,
     when i use StateSetManipulator in mfc like this:
    mViewer->addEventHandler( new osgGA::StateSetManipulator(mViewer->getCamera()->getOrCreateStateSet()) );
 
     It's ok when the program runs,but when the program is closed ,it encounters an error at 
     void __CLR_OR_THIS_CALL _Container_base::_Orphan_all() in file xutility which is a mfc src file.
 
     anyone meets such problem？
