Hey folks, In case you were planning to use the go implementation for your upcoming participation, be aware of this issue with go 1.9.4 -- https://github.com/golang/go/issues/23739
The issue did come up for me on a debian-based system when trying to execute the go code from https://github.com/FiloSottile/powersoftau. I ran into that problem and (as suggested in the github issue for a workaround) downgrading to go 1.9.3 solved the problem. Just thought I'd save you some hassle in case you are hitting the same error.
