Hi, my compiler (Visual Studio 2003) gives an error in access.hpp when I try to serialize an object that has a protected destructor (see summarized compiler output below). If I comment out the call to delete in access::destroy, the compiler does no longer complain and my code seems to work. Is the destroy function (or: the delete call) really needed? Thanks!, Maarten MyClass::MyClass' : cannot access protected member declared in class 'MyClass' boost\archive\detail\iserializer.hpp(105) : see reference to function template instantiation 'void boost::serialization::access::destroy<T>(const T *)' being compiled
