Comment(by cris@…):

 I can certainly have a look in UNIX, although my actual program runs fine
 there with all versions of boost.

 Interestingly (perhaps), I can make my UNIX builds fail with multiple code
 instantiated on 1.42 if using gcc -fvisibility=hidden and explicitly only
 exporting the same symbols as in my windows build.  With 1.39 and the
 -fvisibility=hidden flag I get 'unregistered void cast' on UNIX.  On 1.40
 on Windows with basically the same thing (same exports handled by
 dllexport) I get a working program.

 To use visibility=hidden to work at all I can put pragmas to enable
 default visibility around the boost include macros (export.hpp,
 text_oarchive, text_iarchive).
