Related upstream:
https://github.com/kubernetes/kubernetes/issues/45216

They are using an out of tree patch to Golang:
https://github.com/kubernetes/kubernetes/pull/45879/files#diff-2e328a8d61eb89287c6b3fd10183577c

Comment 2 Seth Jennings 2017-08-07 11:42:43 EDT

Looks like it is fixed in Golang 1.8.3
https://github.com/kubernetes/kubernetes/pull/46429

Can you retry with that version?

Comment 3 Seth Jennings 2017-09-05 10:04:27 EDT

OCP 3.7 builds with golang 1.8.3

Comment 5 Mike Fiedler 2017-10-16 14:49:00 EDT

Discussed with the performance team.   Verification consists of verifying OCP 3.7 is compiled with golang 1.8:

Verified on OCP 3.7.0-0.147.0:
