are you suggesting that if it were class people: public std::vector<person> {.....}; as above the same would be true? not "in practice", "in theory".

Absolutely. See 5.3.5/1 of the standard where this is explicitly called out as undefined behaviour.

5.3.5/1 looks like this in my copy of the standard [snip]

perhaps some other paragraph? this doesn't address anything about derived objects.

D'oh! As others have pointed out, I meant 5.3.5/3. Sorry about that :-( -- Martin Bonner Martin.Bonner@Pitechnology.com Pi Technology, Milton Hall, Ely Road, Milton, Cambridge, CB4 6WZ, ENGLAND Tel: +44 (0)1223 441434
