求助引擎组，升级 1.3.3 之后游戏比较容易 crash 掉，看错误信息好像是跟内存管理有关：
Application Specific Information:
Assertion failed: (_native_js_global_map.find(nativeObj) == _native_js_global_map.end() && "Native Key should not be present"), function jsb_new_proxy, file /Users/nantas/fireball-x/cocos2d-x-prebuilt/cocos/scripting/js-bindings/manual/ScriptingCore.cpp, line 2191.
目前正在持续测试以期待发现规律的重现条件。
