我现在的程序，在Android和Windows平台上都比较表现良好，非常稳定，但在IOS平台上，各种崩溃，比较多的是在Action方面和一些回调脚本函数方面。看似很像JSC的GC的问题导致。你们有没有碰到过这样的情况？这怎么解决呢？

我再找找看栈信息，还碰到过JavaScriptCore子线程的Mark崩溃，都是很怪异的。我后来换成SpiderMonkey, 也比较稳定，但性能不行啊。

是不是说IOS上还不稳定？我想知道现状，免得瞎折腾。
算了，我还是先换SpiderMonkey吧，速度勉强可以接受。等IOS上的jsc的适配稳定下来再换。
奇怪，为何我发现在IOS上，我的应用，SpiderMonkey的运行比JSC快不少，这啥情况？
每个JS VM的优势不太一样，比如SpiderMonkey对native绑定的api调用速度就比jsc，v8块，而ios上jsc的js代码执行速度比SpiderMonkey快很多。
你确定是用了1.8.2版本？1.8.2是有修复 callfunc的问题的。这个有没有复现方法？
能否提供复现方式？目前静态分析很难定位到为题。
你用的版本也是1.8.2么？
我用的是1.8.2 不过我改动了不少代码。
算了，我自己分析吧，估计我改出来的问题。
复现问题太难了，工程太大。
恩，是182正式版的，这个在我这儿也不是必现，偶尔一两次联机调试的时候会发生，我也找不到一点头绪，但Android版确意外的稳定，唯一能确认的就是JSC环境的问题。主要是崩溃发生时，不知道运行了哪段js代码，如果能在引擎层面提供这些信息，我觉得调试就很方便了
不过现在发现，SpiderMonkey和JSC的性能，有时候还不一样，有时sm快，有时jsc快。不过整体上来看，jsc相对平稳，而spidermonkey在长时间运行后，会变慢，可能和GC的累积有关系。
是的，v8和jsc的gc性能是最好的，jsc的gc敏感度非常高，目前对引擎的绑定属于引擎接口的高级绑定，接口复杂度特别高，绑定代码哪里有一点考虑的不周全的地方就有可能在jsc上概率出现问题，而其他js引擎由于相对迟钝，特别是SpiderMonkey，所以比较难出现问题。这也解释了为什么1.6中没有出现的问题，在1.7以上版本ios比较容易概率的出现。这块后续会把绑定层级降低到渲染层面，最大可能降低复杂的绑定关系。
