Re: [boost] Serialization and polymorphic archives

I am interested in addressing this.

Could you send a small example.

Also you might run a couple of tests you isolate what the behavior is 
related to.

a) binary vs text - you ran this test and so it doesn't seem related to 
archive type
b) polymorphic vs non-polymorphic archive type.
c) exported vs non-exported serialization type.
