unfortunately, looks you've run following golang issue: https://github.com/golang/go/issues/18512 . news issue has been fixed. (somewhat) bad news not fixed in go 1.7.x (which used compile binaries).

you can build binaries locally using golang 1.8 or later.

note problem resolve when fab-5461 merged - v1.1.
