Question

在运行2或3秒后，我的Mac上出现代码崩溃，但在centos 7上它没问题，而且，我正在进行1.6.3。

问题：

是什么导致了这种崩溃？
如何避免它？（不从中恢复）

后续堆栈的参数意味着什么？

log.Printf(0x1068d8, 0x6, 0x0, 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
2017/09/02 21:50:01 hello

Answer 1

code 0x0b is 11, which is SIGSEGV.

我在使用Go 1.6.3的onMac之前看到了这个错误：请参阅“go get throws 'fatal error: unexpected signal during runtime execution'” Upgrading would be ideal

有关详情，请参阅go/go issue 17824和cl 32882：

doc/devel/release.html：文档go1.6.3实际上并不支持macOS Sierra。
