Milestone:  To Be Determined                           |   Component:  serialization
  Version:  Boost 1.46.1                               |    Severity:  Showstopper  
 Keywords:  serialization object cross dll             |  
-------------------------------------------------------+--------------------
 If you compare 1_39 and 1_40 here, you can see one 1_39 compares the
 addresses of functions to get type information. Which in 1_40 was 'fixed'
 so that types across DLL's would be matched.

 However this of course breaks archive compatibility with 1_39 as the two
 dll's will have serialized out the CO info twice, and now in 1_40 and
 beyond it'll only try to read it once.. Leaving the file corrupted.

 I'm not even sure how this can be fixed short of storing a flag to
 determine how cobject's compare thats based on archive version where the
 comparison starts...
