I took some time to take a closer look at what the current test failures could be about on the cw-8.3 compiler... before I go on vacation. Specifically I looked at the test_exported errors as those seemed to be common to both the 9 and 8 versions of CW. My findings... I managed to get the export tests to *pass* by modifying the test itself (see attached). The problems boils down to the behavior of CW to only instantiate templates when they are used. This not just applies to class templates, but to template methods. In the case of the exported tests it does not instantiate two important things: a) The serialize template method of non-directly referenced derived classes. Specifically for test_exported: polymorphic_derived1::serialize<test_oarchive>, polymorphic_derived1::serialize<test_iarchive>, polymorphic_derived2::serialize<test_oarchive>, and polymorphic_derived2::serialize<test_iarchive>. Forcing those to be instantiated generates all the rest of the self registration code for the derived classes. This still leaves: b) The archive serialization instance for the needed specializations is also not generated as they are not directly reference. Only the ones for the base class, polymorphic_base, are generated as that's the class used in the actual de/serialize calls. I'm not sure anything can be done about fixing this for the release as the only solutions I can come up with would involve changing the serialization interfaces.
