--- Comment #8 from Bruno Jesus 00cpxxx@gmail.com --- For sake of completeness can you tell your wine version?
This problem is a known issue for a long time but till now nobody ever had a program that worked with such small message lengths so it was never a problem.
The ws2_32/tests can be used to test this since immemorial times.
