很简单的一段代码，go运行一个http服务：

package main import ( "io" "log" "net/http" ) func helloHandler(w http.ResponseWriter, r *http.Request) { io.WriteString(w, "Hello, world!") } func main() { http.HandleFunc("/hello", helloHandler) err := http.ListenAndServe(":8080", nil) if err != nil { log.Fatal("ListenAndServe: ", err.Error()) } }

编译的时候系统日志(/var/log/message)：

机器是Aliyun & CentOS 6.3 64bit & 512M & 1G swap，之前编译其他go代码的时候也发生过这种情况，但是我设置过swap文件之后就可以了。现在不知道怎么解决了。

低端机器连基本代码都不让编译了么555
