In the C Standard, it is stated explicitly that two pointers of the same type which compare equal point to the same object or function. There is no such statment for C++ in the ARM or in the current C++ Committee working draft. I believe this issue needs to be resolved. (Obviously, we need to exclude pointer-to-member from such a requirement.) -- Steve Clamage, TauMetric Corp, steve@taumet.com
