xcode-instruments - Instruments 9.3 是否会导致其他人的应用程序崩溃？

Question

当我使用 xCode 运行我的应用程序时，所有负载都运行良好。当我使用 Activity Monitor 或 Allocations 的分析模板加载 Instruments 并按下记录时，它加载并运行良好。但是，如果我使用 Zombies 或 Leaks，应用程序会立即崩溃。我什至看不到它。然后我在 xcode 中访问崩溃日志，虽然崩溃的原因是
异常类型:EXC_BAD_ACCESS (SIGSEGV)

由于每个报告都不同，因此几乎不可能调试原因。

所以我停止调用电话

StoreManager.getProductIdentifiersFromServer()  

这停止了​​随后的调用

JSONParser.jsonURL(_:jsonType:)  

然后应用程序崩溃

我执行或不调用什么功能似乎都没有关系，我会崩溃。在我看来，它是一个系统调用，而不是我所做的导致崩溃的系统调用。只是我还是 Instruments 9.3 在 Zombies 和 Or Leaks 上崩溃了？

Answer 1

我遇到了类似的问题，我选择 Blank 解决了它模板而不是 Leaks然后我手动添加Allocations和 Leaks使用屏幕右上角的 + 按钮。

它已在 Xcode 版本 9.4 (9F1027a) 上解决
