What operating system

We probably need to ask "which version of operating system are you running?" too. Can you please show us know the output of syscall.GetVersion or key information for helping to scrape MSDN?

Can you show the output of "go test -v -run=TestInterfaces" with golang.org/cl/22521 on the node?

Just a note in case anyone else finds this issue while building 1.6.1 locally;

  • the test still fails in tag "go1.6.1" but it's innocuous
  • confirmed it is fixed in current master branch, which will become go1.7

@maruel,

I strongly believe that you misunderstand something. This issue never happens on go1.6 and below. Probably #14859 ?
