Double check that a is polymorphic - that is, that it has at least one virtual function. Then get back to us.

Also, there is an issue in the documentation. In the "Pointers to Objects of Derived Classes" section, it has example registration code:
main(){ ... ar.template register_type<derived_one>(); ar.template register_type<derived_two>(); base *b; ar & b; }
I'm guessing that is supposed to be:
main(){ ... ar.register_type<derived_one>(); ar.register_type<derived_two>(); base *b; ar & b; }
nope, its correct. This is a little known quirk of C++ syntax. Your second version won't compile on the most conforming compilers.
Not according to Comeau: "ComeauTest.c", line 16: error: the "template" keyword used for syntactic disambiguation may only be used within a template
