func _Cfunc_puts(p0 *_Ctype_char) (r1 _Ctype_int) {

	}

The hexadecimal number is a hash of cgo's input, chosen to be
deterministic yet unlikely to collide with other uses. The actual
function _cgo_be59f0f25121_Cfunc_puts is implemented in a C source
file compiled by gcc, the file x.cgo2.c:

      "Invalid URL host: \"[0:0:0:0:0:1:0.0.0.000001]\"",
    )
  }

  @Test
  fun hostIpv6WithIpv4SuffixWithHexadecimalPrefix() {
    // Chrome interprets a leading '0x' as hexadecimal; Firefox rejects them. (We reject them.)
    assertInvalid(
      "http://[0:0:0:0:0:1:0.0x10.0.0x10]/",
      "Invalid URL host: \"[0:0:0:0:0:1:0.0x10.0.0x10]\"",
    )
  }
