From version 1.34 to 1.35, the export of classes was modified so that all the archives did not need to be included before calls to BOOST_CLASS_EXPORT. I don't know why this was a problem to begin with.
Anyway, this feature used to work on SunCC but with the new changes, there is a regression. This is caused by the dependence on ADL to instantiate the ptr_serialization_support members: SunCC just doesn't do it. So the instantiations never occur and you get an assertion failure when running the serialization tests under debug: Assertion failed: it != boost::serialization::singleton< oserializer_map<Archive> >::get_const_instance().end(), file vendor/boost_1_37_0/boost/archive/impl/archive_pointer_oseri\ alizer.ipp, line 64 I know how to fix it (instantiating manually for each Archive,Serializable pair, not a huge problem). I would suggest that Boost Serialization should have a fallback mechanism for these compilers. Perhaps along the lines of the old export functionality where the user would define the archives they are interested in. Thoughts?
