Section 4.1.1 says:
Last line of the algorithm: 5. Let v = v_1 (mod n)
It should say:
5. Let v = v_2 (mod n)
Notes:
With the actual version of the RFC, the output of the algorithm 4.1.1 with the test cases input is v = 5ab5b7a6d72fa91bd01df98e29afb77f05e7b880, which doesn't correspond with the expected output.
However, with the correction, the output is correct:
v = 79317c1610c1fc018e9c53d89d59c108cd518608
