Answer 1 · 2016-02-18T02:19:46.000Z

Thanks for the report. It looks like it a go-duktape issue. Could you tell me the Go version and os/arch,

Answer 2 · 2016-02-18T03:33:34.000Z

Yep.

go 1.5 version devel +0417872 Mon Nov 23 04:04:07 2015 +0000 darwin/amd64

Answer 3 · 2016-02-18T06:16:05.000Z

Thanks. Related issue already there https://github.com/olebedev/go-duktape/issues/34. If you still need to make go-starter-kit work please use Go 1.5.3. I'll fix it asap.

Thanks a lot for the fix. I just updated the master. It works!! with Go 1.6
