This was caused by not supplying a correct pointer to where fread should read. The files are now opened in binary mode (which I have under stood can cause problems between different OS if it is not done). I also check for EOF when I compare data from fread. Previously the checking for correct amount of bytes read failed when the end of the file had been reached.
