creator频繁切换场景，会崩溃

Creator 2.x
#1

创建两个场景，在两个场景间频繁切换(一般快速切换5到6次就出现)，程序崩溃
崩溃日志：

#2

看不出什么原因，你测试的creator版本是多少，可以附上你的切换场景部分的代码吗？可以来个demo最好了。

#3

cc.director.preloadScene(sceneName, function () {
LayerUtil.closeLoadLayer();
cc.director.loadScene(sceneName,function(){
cc.director.getScene().name = sceneName;
});
});
切换场景的代码

#4

找到问题了，是因为在onload内有加载远端图片操作
