TestAllMachinePorts fails on gccgo

Using the gccgo compiler, TestAllMachinePorts in apiserver/uniter/uniter_v1_test.go fails:

uniter_v1_test.go:400:
    c.Assert(result, gc.DeepEquals, params.MachinePortsResults{
        Results: []params.MachinePortsResult{
            {Error: apiservertesting.ErrUnauthorized},
            {Ports: expectPorts},
            {Error: apiservertesting.ErrUnauthorized},
            {Error: apiservertesting.ErrUnauthorized},
            {Error: apiservertesting.ErrUnauthorized},
            {Error: apiservertesting.ErrUnauthorized},
        },
    })
...unreadable junk...

But basically it's:

network.PortRange{FromPort:1, ToPort:8, Protocol:"udp"}
network.PortRange{FromPort:100, ToPort:200, Protocol:"tcp"}
network.PortRange{FromPort:10, ToPort:20, Protocol:"udp"}
network.PortRange{FromPort:201, ToPort:250, Protocol:"tcp"}

!=

network.PortRange{FromPort:100, ToPort:200, Protocol:"tcp"}
network.PortRange{FromPort:10, ToPort:20, Protocol:"udp"}
network.PortRange{FromPort:201, ToPort:250, Protocol:"tcp"}
network.PortRange{FromPort:1, ToPort:8, Protocol:"udp"}
