golang log.Printf崩溃

在运行2或3秒后,我的mac上的代码崩溃,但是在centos 7上它没关系,而且,我正在运行1.6.3.

问题：

>是什么导致了这种崩溃？
>如何避免它？ (没有恢复)
>后续堆栈的参数意味着什么？

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

签名是：

Print(v ...interface{})

崩溃的代码：

package main
import (
    "log"
)

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

它将在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
