‍

分析：

关键特征：
1. onEnter 走完，并没有 crash 在 onEnter 中的 addChild 上；js 代码：
2. 堆栈中未出现嵌套的 addChild 过程，且测试时使用的 new cc.Node(), 可以排除是当前子节点异常；
3. spidermonkey 接口流转正常结束，js_cocos2dx_Node_onEnter 中 cobj 的有效性检查通过；
4. 如果去掉 onEnter 中的 addchild 普通关卡和 HR 关卡均无异常，可以排除是其他节点导致的；
5. 关卡场景对象本质上是一个 cc.Node；
  1. 仅当在关卡根节点的 onEnter 中直接对关卡根节点做 addchild 操作时会触发 crash；
  2. 在关卡根节点的 onEnter 中操作其他子节点 addChild 无异常；
  3. 非关卡根节点（cc.Node）的 onEnter 中为当前节点 addChild 无异常；
堆栈定位：
关卡根节点的 js onEnter 方法执行完后再次调用根节点 cobj 的 onEnter 方法时，遍历关卡根节点时 child 出现了空指针；；
推测：
addChild 出现了子节点的 jsobj 添加成功，但 cobj 状态不同步、为 nullptr 的情况；

‍

解决方案：

避免在关卡场景的 onEnter 方法中直接对关卡根节点做 addChild 操作：

可避开 onEnter ，在 ctor 或其他逻辑位置 addChild；
如必须在 onEnter 中 addChild，需避免直接操作根节点；
