这两天遇到一个诡异bug，游戏进行中crash
这个crash只有在Release环境，64位的机器上运行，非调试模式下（xcode不在run的状态）才会发生，其他时候都不会发生
Application received signal SIGSEGV

已经通过某种方法在第5条的函数里找到了崩溃的地方，
这是crash的那行， pObstacleSprite->getModel()->getID()，
分解后，在getID()崩溃，
pObstacleSprite是一个障碍物精灵 class CObstacleSprite : public cocos2d::CCSprite
getModel()获得一个精灵数据模型 class CObstacle : public CGameObject, public cocos2d::CCObject，CGameObject是个纯虚类
getID()是获取CObstacle类的一个int型私有成员变量
看了相关的源码后实在找不到在这种特殊情况才会崩溃的原因
ps：引擎还是用旧的2.0版的
