I'm getting a ubsan test error in uuid/test/test_serialization - is the code in that test using archive the right way?

I see the same thing in a ubsan build of DateTime, so I think this might be in serialization, not in Uuid or DateTime. testing.capture-output ../../bin.v2/libs/date_time/test/testgreg_serialize_xml.test/gcc-7/debug/cxxstd-03-iso/testgreg_serialize_xml.run ====== BEGIN OUTPUT ====== Running xml archive tests ../../boost/archive/detail/interface_oarchive.hpp:47:16: runtime error: downcast of address 0x7ffc8d8a2a10 which does not point to an object of type 'xml_oarchive' 0x7ffc8d8a2a10: note: object is of type 'boost::archive::xml_oarchive_impl<boost::archive::xml_oarchive>' 48 7f 00 00 48 b8 60 46 48 7f 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ^~~~~~~~~~~~~~~~~~~~~~~ vptr for 'boost::archive::xml_oarchive_impl<boost::archive::xml_oarchive>' EXIT STATUS: 1 ====== END OUTPUT ====== Here's the command line I used with uuid to isolate it to one test: jking@ubuntu:~/boost/libs/uuid/test$ ../../../b2 toolset=gcc-7 variant=debug cxxflags=-fno-omit-frame-pointer cxxflags=-fsanitize=undefined cxxflags=-fno-sanitize-recover=undefined linkflags=-fsanitize=undefined linkflags=-fno-sanitize-recover=undefined define=BOOST_UUID_LIMITED_BENCH -q test_serialization - Jim
