 Boost::crc fails if Visual C++'s "/RTCc Convert to smaller type checks" is
 enabled

 I would suggest to change crc_helper::index() from
 {{{
 static  unsigned char  index( value_type rem, unsigned char x )
 { return x ^ rem; }
 }}}
 to
 {{{
 static  unsigned char  index( value_type rem, unsigned char x )
 { return x ^ (rem & 0xFF); }
 }}}
