From https://build.golang.org/log/a1e647502ffe3ced34891a80b7bc714aebdf2ab3:

--- FAIL: TestTCPListener (0.00s)
    listen_test.go:72: skipping tcp  test
    listen_test.go:72: skipping tcp 0.0.0.0 test
    listen_test.go:72: skipping tcp ::ffff:0.0.0.0 test
    listen_test.go:72: skipping tcp :: test
    listen_test.go:90: tcp 127.0.0.1 should fail

(Note that this was previously reported in #22020, so this failure mode is apparently quite old.)

I notice that several of those tests also omit the localhost address:
