Comment (by Mika Fischer <mika.fischer@…>):

 Well, with 1.55.0, the existing test case (test_no_rtti.cpp) already
 triggers this bug (and #8400) ''if it is compiled without RTTI''. So
 getting the existing test case to work when RTTI is disabled in the
 compiler would probably go a long way towards fixing the existing issues
 with RTTI.

 I'm pretty sure #10280 is also triggered by the test case, but with
 1.56.0, it does not compile for me

 We have decided not to pursue boost serialization without RTTI any further
 at this time. Buf if you have specific questions or requests, I'll see
 what I can do to help.
