##### Testing without libgcc.

As far as I remember, I encountered this failure twice. In the source code, 150 is hard coded, but I'm not sure the value is reasonable or not:

    for _, tt := range []*CertPool{sysRoots, execRoots} {
        if tt == nil {
            t.Fatal("no system roots")
        }
        // On Mavericks, there are 212 bundled certs; require only
        // 150 here, since this is just a sanity check, and the
        // exact number will vary over time.
        t.Logf("got %d roots", len(tt.certs))
        if want, have := 150, len(tt.certs); have < want {
            t.Fatalf("want at least %d system roots, have %d", want, have)
        }
    }

Does this issue reproduce with the latest release (go1.7.4)?

I didn't try.
