Description of problem: In a pristine rawhide mock chroot, with golang-bin 1.9-0.beta2.1.fc27: $ go --version panic: runtime error: index out of range Expected results: Go shouldn't panic. Subsequently all go build fail with this error. It happens on Koji too, see for example https://koji.fedoraproject.org/koji/taskinfo?taskID=21435093 : Go fails with this error on all arches.
This doesn't seme to be problem currently in rawhide golang-bin-1.9-1.fc28.x86_64 Closing. Please reopen if that's still an issue for you.
