The code is:

package main

/*
int teste() { return 2 + 1; }
*/
import "C"

func main(){
    println(C.teste()); 
}

It does seem like that should work. The exit code is 0xc0000005, access violation (like Unix SIGSEGV).

@WesleiRamos, what versions of Windows are you using? Thanks.

This works for me on:

go version devel +bba1ac4 Thu Oct 27 22:55:30 2016 +0000 windows/386

with both gcc (GCC) 4.8.1 and gcc (tdm-1) 5.1.0.
I use Windows XP.

Is there a reason you are using 32-bit x86 with Windows 10 instead of 64-bit x86? I wouldn't think Windows 10 would run on any 32-bit-only hardware.

I wonder if maybe something somewhere is getting confused about whether it should be 32-bit or 64-bit code.

I switched compiler and it worked, to version 4.7.1 of gcc.

Sounds like this is resolved. Let me know if I'm confused.
