Fix:

Instead of this:
long readBytes( char* fname, FILE* fp )
{
        //TODO: see setbuf, setvbuf se possono migliorare le performances.
        static int nb;
        //fseek ( fp , 0 , SEEK_SET ); //rewind
        freopen( fname, "r", fp );
        fscanf( fp, "%i", &nb );
        return nb;
}

Use:

long readBytes( char* fname, FILE* fp )
{
        //TODO: see setbuf, setvbuf se possono migliorare le performances.
        static long long nb;
        //fseek ( fp , 0 , SEEK_SET ); //rewind
        freopen( fname, "r", fp );
        fscanf( fp, "%lld", &nb );
        return nb;
}
