@hktalent I cannot reproduce the issue on Windows, OSx, and Linux 64bit. Could you provide more info about the execution environment? Is the version you are compiling from the master branch without any customization?

Change the go version and try again.

Confirmed to work on osx, Linux, and windows. Converting to a discussion as it seems not reproducible for further investigation.
