Question

Xcode 4.6.1在我的新mac mini上使用LLDB调试器继续崩溃。任何人都可以帮我解决发生的事情吗？可以使用GDB，但我宁愿使用默认调试器，因此每次运行/测试新项目时都不需要更改它。

我已经阅读了有关编辑/ etc / hosts以获得127.0.0.1 localhost的内容，但它无效。

以下是我的Xcode崩溃时的一些细节。

Answer 1

也发生在我身上。 Esp与SIGABRT在主类。我被建议调试。我确实尝试过lldb调试。它适用于一个应用程序。您需要找到引发错误的寄存器。要找到你需要先输入调试窗口（当它的lldb错误时！）

register read

然后你会发现它引发注册的错误。然后按照以下说法进行操作如果eax是注册表..

po $eax
po [$eax class]
po [$eax name]
po [$eax reason]

然后你就会知道你必须在代码中做出哪些改变。希望它适合你。
