通过第三方的崩溃分析，崩溃率15%，都是在app启动5秒内崩溃的，系统90%都是13.1.3，详细日志如下

@jare @minggo 引擎组的大佬们能出来瞅瞅嘛，日活几万的产品伤不起啊！

重现截图

#4

暂时将2.2.0里面的v8屏蔽了，性能差了，但是解决了大量崩溃问题。
config.hpp里面 修改为
#if TARGET_OS_IOS
//#ifdef arm64
// #define SCRIPT_ENGINE_TYPE SCRIPT_ENGINE_V8
//#else
#define SCRIPT_ENGINE_TYPE SCRIPT_ENGINE_JSC
//#endif
#endif
还是希望引擎组的重视一下这个问题， 启动app 5秒内调用
se::ScriptEngine::getInstance()->evalString(“console.log(“hello world”)” , -1 , ret);
启动十次左右崩溃一次

#5

测试并没有复现这样的情况，可否在heloworld基础上提供个复现demo，尽量排除自身项目的干扰

#6

hello world项目还是重现了，但是概率太小了，可能循环操作100次左右才出现一次，就不提供demo了把:smile:。
我提到的问题是因为线程不同步的问题，把oc里面执行脚本的操作放在主线程里面就可以了，谢谢引擎大佬kenshin的关注。
