If one can't read older archives, its the result of an oversight on our part.

In order to help us discover where the oversight occurred the following 
would be helpful.

a) information as to whether the problem occurs only with binary archives
or with all types of archives.

b) Information as to which new version of the serialization library has 
manifested the problem.  It could be the 1.35 in the trunk or it could be
1.36 at www.rrsd.com.  Upon reading your post, it has occurred to me that
a made a change in 1.36 that could cause this behavior so I plan to look into 
this.  But I would like to know if it occurs with 1.35 as well

c) It would be if you could submit a small test case, including file
generated with previous version.

  Could you please elaborate on this a bit? 

  I am currently using boost 1.34.0, and am using binary archives. If we release 
  software now that generates binary archives, and at a later stage, if we upgrade the 
  boost version, will we not be able to read back the old binary archives? How do we 
  ensure that on upgrading boost we can still read back old binary archives? 

  Thanks
