I once had a similar problem, and this is what I did: I downloaded
OpenSSL source code, and added some debugging printf's to ssl/s3_enc.c
(ssl3_generate_master_secret and ssl3_generate_key_block functions),
and then tested my implementation against the openssl s_client/s_server
command line tools.

Best regards,
