 from CryptoStream.cs: Write(..) (from 0.96 release sources)
 // transform all except the last block (which may be the last block
 // of the stream and require TransformFinalBlock)
 
 So, perhaps this isn't abug afterall (??...)

+Well this is really a bug as MS implementation would process all the
+64 bytes with the same source code. Sadly CryptoStream has tons of
+strange behaviours which requires not to process the current block
+unless we are sure it's not the last one. Somehow this isn't the case
+in your sample code.
+
+Note that Flush doesn't call FlushFinalBlock as this would break any
+further use of the stream (nothing can be encrypted/decrypted after
+the final block).
