The server sends a number of columns to the client. It uses a limited "fast" function for that instead of the general one. This fast function cannot send numbers larger than 2 bytes. This causes the client to expect smaller number of columns. The client writes outside of the allocated memory buffer as a result. Fixed the server to use the general function to send column count. Fixed the client to check the column count before writing column data.
