Section 7.2 7.3 says:

                           Kseq = HMAC(Kss, "fortybits", (int32)0);
                                        // len includes terminating null
                           memset(Kseq+7, 0xab, 7)

It should say:

                           Kseq = HMAC(Kss, "fortybits", (int32)0);
                                        // len includes terminating null
                           memset(Kseq+7, 0xab, 9)

Notes:

applies both to section 7.2 and 7.3, confirmed by Larry Zhu
