Following code crash on my mac after running 2 or 3 seconds, but it's okay on centos 7, and, I am on go 1.6.3.
Questions:
What does arguments of following stack means?
log.Printf(0x1068d8, 0x6, 0x0, 0x0, 0x0)
the signature is:
Print(v ...interface{})
The crashed code:
package main
import (
"log"
)
func main() {
for {
log.Printf("hello")
}
}
It will crash in 10 seconds, and prints:
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

code 0x0b is 11, which is SIGSEGV..
I have seen that error before onMac with Go 1.6.3: see "go get throws 'fatal error: unexpected signal during runtime execution'".
Upgrading would be ideal.
See go/go issue 17824 for more, and cl 32882:
doc/devel/release.html: document go1.6.3 doesn't actually support macOS Sierra.
