golang log.Printf crash

Question

運行2或3秒後，在我的mac上發生以下代碼崩潰，但在centos 7上運行正常，並且我正在運行1.6.3。

問題：

1. 是什麼原因造成這樣的崩潰？
2. 如何避免它？ （不能從中恢復）

3. 以下堆棧的參數意味着什麼？

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

   的簽名是：

   Print(v ...interface{}) 
   

墜毀的代碼：

package main 
import (
    "log" 
) 

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

它會在10秒內崩潰，並打印：

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之前的錯誤：請參閱「go get throws 'fatal error: unexpected signal during runtime execution'」。
Upgrading would be ideal。

見go/go issue 17824更多，和cl 32882：

doc/devel/release.html：文件go1.6.3實際上並不支持MacOS的塞拉利昂。
