问题 I notice there is one line *(*int)(nil) = 0 in function throw //go:nosplit func throw(s string) { // Everything throw does should be recursively nosplit so it // can be called even when it's unsafe to grow the stack. systemstack(func() { print("fatal error: ", s, "\n") }) gp := getg() if gp.m.throwing == 0 { gp.m.throwing = 1 } fatalthrow() *(*int)(nil) = 0 // not reached } What does *(*int)(nil) = 0 means? and since this line *(*int)(nil) = 0 could NOT be reached, why it is here? any special

如果要深入了解go-ethereum项目的实现与机制，看源代码是必不可少的。今天这篇博客就简单介绍一下如何在本地搭建项目的开发环境。 GO语言环境搭建以win8为例，访问地址 https://golang.org/dl/ ，下载windows版本。直接执行安装，默认会安装到C:\Go目录下，将 c:\Go\bin 目录添加到 PATH 环境变量中。执行命令，验证安装配置成功： C: \Users \Administrator>go version go version go1.7.4 windows/amd64 1 2 开发ide 本篇博客以intellij idea 15为例。首先安装go语言插件（地址 https://github.com/go-lang-plugin-org ）。进入idea的settings，选择plugins， Browse repositories，搜索go lang。具体操作如下图：点击install，安装Go Lang Plugin。上图仅为参考，因为截图中的idea已经安装过插件了。如果无法直接下载，可在Manager repositories中配置一下地址： https://plugins.jetbrains.com/plugins/alpha/5047 然后再尝试下载。如果因网路原因无法下载，可考虑在 https://plugins

Does Go guarantee constant addresses?

阅读更多关于 Does Go guarantee constant addresses?

问题 Given an object obj is there a guarantee that uintptr(unsafe.Pointer(&obj)) will always evaluate to the same value regardless of when it is called? Of course, Go guarantees that if you take two pointers to the same object, they will always compare equal. It might be possible though that an implementation moves an object in memory and transparently updates all pointers to it. This is interesting if you consider garbage collection strategies like Mark-and-Compact. Would an implementor be
