#5499: Serialization backward compatability

     Type:  Bugs                         |      Status:  new          
Milestone:  To Be Determined             |   Component:  serialization
  Version:  Boost 1.46.1                 |    Severity:  Showstopper  
 Keywords:  serialization compatability  |  
-----------------------------------------+----------------------------------
 Boost 1.33.1 serializes class_id_type as int_least16_t (archive version
 3). Current boost tries to load it as int for archive of version 6 and
 earlier. On my platform (VS2005) int is 32 bits, hence the deserialization
 fails.

 The attached code creates and successfully loads 'out.boost103301.dat'
 when compiling with boost 1.33.1 and crashes due to failed assert in
 class_id_type constructor when loading with boost 1.46.1.

 I'm upgrading from 1.33.1 to boost 1.46.1 now, so I mark it as
 'Showstopper'.
