golang log.Printf crash

Question

运行2或3秒后，在我的mac上发生以下代码崩溃，但在centos 7上运行正常，并且我正在运行1.6.3。

问题：

1. 是什么原因造成这样的崩溃？
2. 如何避免它？ （不能从中恢复）

3. 以下堆栈的参数意味着什么？

   log.Printf(0x1068d8, 0x6, 0x0, 0x0, 0x0) 
   

   的签名是：

   Print(v ...interface{}) 
   

坠毁的代码：

package main 
import (
    "log" 
) 

func main() { 
    for { 
     log.Printf("hello") 
    } 
} 

它会在10秒内崩溃，并打印：

2017/09/02 21:50:01 hello 
2017/09/02 21:50:01 hello 
2017/09/02 21:50:01 hello 
2017/09/02 21:50:01 hello

Answer 1

code 0x0b is 11, which is SIGSEGV.。

我看到onMac和Go 1.6.3之前的错误：请参阅“go get throws 'fatal error: unexpected signal during runtime execution'”。
Upgrading would be ideal。

见go/go issue 17824更多，和cl 32882：

doc/devel/release.html：文件go1.6.3实际上并不支持MacOS的塞拉利昂。
