Question on the usage of the crc:

I run the following code:

  boost::crc_slow<1> crc_1(1,0,0,false,false);

  std::bitset<7> t = 108; //("1101100");
  std::cerr << t << std::endl;
  for (int i=t.size()-1; i>=0; --i)
    crc_1( t.test(i) );
  std::bitset<7> s = *crc_1; //("1101100");
  t |= *crc_1;
  std::cerr << t << std::endl;
  std::cerr << s << std::endl;

And get this result:


Indicating that the remainder returned by crc_1 is way to big.

Shouldn't the remainder be only one bit? Or am I misunderstanding the

Subj: [boost] Review Request: CRC

I asked around a week ago if there was any problems with my CRC classes
("" in the vault). Since no one has said anything, I want to put the
CRC stuff under formal review.

Besides me researching and writing the classes, Jens Maurer gave me advice
on GCC compatibility problems. (I'm mentioning this because of the "an
active boost member not connected with the library submission must volunteer
to be the 'Review Manager' for the library" clause in the review process. I
don't know if this slight aid disqualifies Jens or not.)
