--- Comment #2 from Andrew Stern <andrew.stern at itg dot com> --- >>Is this valid as *this at this point is just a Baseclass type (and does not >>have a Subclass type. I believe the code to be valid since the template generates both the Baseclass and Subclass. The Subclass object is really just the same object as the Baseclass and the sizeof operator seems to give the correct values. Note that the code compiles and runs and the correct member functions get called. If you think this is the issue what is the correct method to get the Subclass type. Note the line also is consistent with the code located at: http://eli.thegreenplace.net/2011/05/17/the-curiously-recurring-template-pattern-in-c/ Specifically: const Derived& d1 = static_cast<const Derived&>(o1);
