关于运行实例不成功的疑惑-create and driving a character system

tingsky

大家好，
我正在通过<OpenSceneGraph 3.0 Beginner's Guide> 学习OSG。
在文章中的Chapter 8 ： Animating Scene Objects 中的示例“Time for action - creating and driving a character system”结果不成功，特来请教。
参照说明运行程序后，bignathan.osg 正确地显示在屏幕上， 但控制台输出的内容异常，并不是文章中的列举 bignathan.osg 中的动作名称列表，大家有遇到类似的情况吗？
OSG version : 3.0.1
运行环境： vMware 10  + Windows XP
控制台输出信息：

这里再罗嗦地把测试程序代码贴出来：
#include <osgAnimation/BasicAnimationManager>
#include <osgDB/ReadFile>
#include <osgViewer/Viewer>
#include <osg/ArgumentParser>
#include <iostream>



int _tmain (int argc, char* argv[])
{
        osg::ArgumentParser arguments( &argc, argv );

        bool listAll = false;
        std::string animationName;
        arguments.read("--animation", animationName);

        if (arguments.read("--listall")) listAll = true;

        osg::ref_ptr<osg::Node> model = osgDB::readNodeFile("bignathan.osg");
        if (!model) return 1;

        osgAnimation::BasicAnimationManager* manager =
                dynamic_cast<osgAnimation::BasicAnimationManager*>
                (model->getUpdateCallback());
        if (!manager) return 1;

        const osgAnimation::AnimationList& animations =
                manager->getAnimationList();
        if (listAll) std::cout << "**** Animations ****" << std::endl;
        for (unsigned int i=0; i<animations.size(); ++i)
        {
                const std::string& name = animations[i]->getName();
                if (name == animationName)
                        manager->playAnimation(animations[i].get());
                if (listAll) std::cout << name << std::endl;
        }

        if (listAll)
        {
                std::cout<< "************************" << std::endl;
                return 0;
        }

        osgViewer::Viewer viewer;
        viewer.setSceneData(model.get());
        return viewer.run();

}
