我正在阅读 Sau Sheong Chang (Manning, 2016) 所著的“Go Web Programming”一书的一些教程代码，并在尝试运行go build一次时遇到“致命错误：运行时执行期间出现意外信号”，然后尝试一分钟后第二次没有尝试任何东西并且它起作用了。 我正在构建的代码在这里。

我想重申：这种情况只发生过一次。 随后运行的go build _没有改变任何东西_按预期工作。 不幸的是，除了剪切和粘贴下面的堆栈跟踪之外，我几乎没有任何信息可提供，因为我无法重现。 我看到一个问题已被打开，似乎是相同的错误，但该线程表示如果它出现在真实硬件（是：2013 MacBook Pro）上，则应打开一个新问题。
