我如何阅读崩溃报告以了解发生的情况？

崩溃报告非常适合找出程序发生了什么情况，并取决于可能修复它们的情况（例如，Final Cut崩溃试图使用超过2.5GB的内存-请关闭一些项目）。它们对开发人员来说最重要，因此请务必将其传递，就好像问题是一个错误一样。关于超级用户处理内核恐慌的一个相关问题也可能有用。

在StackOverflow上对该主题的另一个很好的讨论，它也链接到此Apple Tech。注意

我将分解示例崩溃报告：

Report Version:  6

开头的几行只是告诉您崩溃的原因，时间和开始时间（父进程）。

该信息不是很有用，可以删除-只是说明有多少次崩溃以及自上次崩溃报告保存以来已经发生了多长时间。

这是您要查找的主要信息-异常类型可以告诉您哪种错误导致程序崩溃（可以是您可以修复的错误或实际的错误），更具体地说是什么线程崩溃了。如果您拥有“特定于应用程序的信息”，那么它不会受到损害，因为它可以使您了解崩溃时正在使用的内容。

上面的5条崩溃信息线程对您作为用户完全没有用，因为它们与容易识别的崩溃无关。但是，开发人员在处理并发（线程）问题时可能需要知道它在做什么。

这就是肉和土豆-前几行代码让您大致了解正在发生的情况-在这种情况下，我的更新下载完成后，出现了严重的错误。

通常，这里的最后一个细节对于用户来说并不那么重要-但是它们为开发人员提供了一些很好的背景信息。

第2行表示“软件更新”正在运行，并显示了从中加载的映像（路径）。第6行，“父进程”表示它是由启动守护程序运行的，即计划运行，而不是由您手动启动的。

异常类型SIGSEGV是段冲突-程序试图访问操作系统分配的内存以外的其他内存。可能是因为它使用了未初始化的指针，或者返回地址或其他一些指针被覆盖，如果程序堆栈上的缓冲区被溢出，可能会发生这种情况。

没有源代码和负载映射，其余信息几乎没有用，即，试图找出崩溃如何发生的程序员感兴趣，但对我们其他人没有太大用处。
