Dup of #19734?

Look like the other topic is pretty random depending on the c library used.
Here I just use go build and there is just an import "C".
There is no use of any c functions.

I also tried using a simple printf, the result was the same.

This started to occur since I updated to go 1.8.

using go build -ldflags -s solve the problem but i doubt this should be the default behavior since it's not documented anywhere.

just saw there was a go update.
I tried it and look like it's fixed.
👍 guys.
