When I test the assertion ----
"Encryption/Decryption should perform correctly under the situation that the buffers used for storing plain text and cipher text are overlapped or the same." for feature "Cipher".
I found that CFB24, ofb48, ofb56 mode failed in Encryption step. The same to
CFB48, CFB56 and OFB24. But it work with CFB40 since the length of plaintext is 80 bytes.

see the attached logfile for detail information.
