出于某种原因，由于用户数量较少(例如几百分之一)，应用程序在 Snow Leopard 10.6.3 上以 64 位模式运行时似乎会崩溃
我已附上堆栈跟踪。 com.apple.AppKit 中的崩溃似乎是在随机位置和随机时刻随机发生的。 还有人有过类似的经历吗？
使用Xcode 3.2.2的GCC编译器
用户的第 1 次崩溃

奇怪的是，当这些用户在 32 位模式下运行代码时，崩溃似乎消失了。
崩溃显然是在 32 位模式下仅在 AppKit 本身内部启动后才会触发，就像 NSThread sleep 的调用堆栈深处一样。
其他一些开发人员也看到了同样的情况: http://lists.apple.com/archives/objc-language/2008/Sep/msg00111.html
无法理解为什么以及是否可以获得更多背景信息。
最佳答案
我已添加 Apple 支持请求，他们确认这是 Mac 操作系统问题。 如果他们报告更多信息，将发布更多信息。
关于objective-c - 64 位模式下偶发 EXC_BAD_INSTRUCTION (SIGILL)，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/2753172/
