我有一个应用程序，它只对我的一个测试人员崩溃——没有其他人的。但对她来说，它一直在崩溃。这很奇怪。
详细信息：
她在 iPhone 4 和 iPhone 3Gs
上应用程序在两部手机上的所有操作系统上
崩溃 无论联系人是如何创建的，应用程序都会崩溃
当她向我发送她的联系人时，他们在我的 iPHone 4 和我的 3G 上都可以正常工作（不是 s)
她是唯一一个发生过崩溃的人，并且在两部手机和所有操作系统中都是一致的
她已经卸载并重新安装了应用程序和配置文件
她正在将她的 iPhone 与 Windows 机器版本的 iTunes 同步
当我们使用 ABPeoplePicker 时会发生崩溃。
从她的角度来看，似乎在她选择电话号码的那一刻，应用程序就崩溃了。当然，她当时不在我们的应用程序中。她在 Apple 提供的 ABPeoplePicker 导航视图中。从重新符号化的崩溃日志来看，在我看来，当它试图返回我们的应用程序时，它实际上正在崩溃。换句话说，我在崩溃日志中找不到任何提及我们的应用程序实际上对崩溃负责（见下文）。看起来它无法获取所选电话号码的索引，然后在尝试弹回我们的应用程序时失败，但这充其量只是猜测。我已经阅读了 Apple 文档并尝试尽职尽责地学习如何阅读崩溃日志，但我仍然感到困惑。以下是我的问题：
1. 有谁知道异常代码：0x00000000, 0x00000000 是什么意思？
2. 我是否正确假设第 9 行是指实际问题的地方？如果是这样，我如何理解 objc_exception_throw + 64 的含义？
3. 谁能解释一下这个崩溃日志所说的问题是什么？
