I imagine that the only reason for such behaviour could be some mismatch in compilation
options between the library and the program. Does the problem persist if you try
a later release? Do you have RTTI enabled in your project? Do you have any options
affecting ABI set to values different from default (e.g. alignment)

Also, are you sure you don't have *two* boost installations, of different version,
and use headers from one installation and libraries from another?
