Robert Ramey	897dec4c01	imported/implemented boost/serialization/variant and test_variant imported/implemented boost/serialization/variant now contains code for serialization of boost::variant, boost::variant2 and std::variant. Care has been taken to depend only on the public interfaces of these types. Hence, it is reasonable to hope that the archives are compatible in that one type could be saved and subsequently loaded into a compatible type. Hopefully this will be useful in some way. At a minimum it minimizes code duplication.	2023-09-18 10:49:21 -07:00

Christian Mazakas	6388138a0c	Fix invalid vptr access in extended_type_info_no_rtti constructor Initializing a base class in the initializer list with a member function in the derived is invalid in gcc as the object isn't fully-formed We instead just inline the body of `get_key()` which avoids the issue.	2023-09-11 13:59:51 -07:00
Christian Mazakas	8d0fbb79f3	Fix invalid downcast in ~xml_oarchive_impl The destructor of the xml_oarchive_impl winds up calling `this->windup()` which in turn invokes `this->This()->...` which essentially static_cast's to a Archive, which by this point in time is long-since destructed. By simply inlining the implementation of windup(), we avoid the UB and minimize the required code changes	2023-09-11 13:59:51 -07:00
