why crash when show 2D map?

osgEarth Version (required):2.8

What is the problem?

std::string wktString = "EPSG:3857";            //wgs84
    osgEarth::ProfileOptions profileOpts;
    profileOpts.srsString() = wktString;

    // 设置缓存目录
    osgEarth::Drivers::FileSystemCacheOptions cacheOpts;
    std::string cacheDir = path.toStdString() + "/data/tmp";
    cacheOpts.rootPath() = cacheDir;

    osgEarth::MapOptions mapOpts;
    mapOpts.cache() = cacheOpts;
    mapOpts.coordSysType() = osgEarth::MapOptions::CSTYPE_PROJECTED;
    mapOpts.profile() = profileOpts;

    // 创建地图节点
    osg::ref_ptr<osgEarth::Map> map = new osgEarth::Map(mapOpts);

    osg::ref_ptr<osgEarth::MapNode> mapNode = new osgEarth::MapNode(map);

    osgEarth::Drivers::GDALOptions gdal;
    gdal.url() = path.toStdString() + "/data/world.tif";;   // 二维地图资源路径
    osg::ref_ptr<osgEarth::ImageLayer> layer = new osgEarth::ImageLayer("mapImage", gdal);
    map->addImageLayer(layer);
    root->addChild(mapNode);

when program run line osg::ref_ptr mapNode = new osgEarth::MapNode(map); app crash,why?

Where does it crash? Do you have a stack trace?
