I think that Dave's point is that in new(h.storage) Foo; there is a char* -> void* implicit conversion as placement new takes a void*. So the placement new performs char* -> void* -> Foo* (by constructing a Foo at (void*)h.storage), which - in theory - might not be the same as char* -> Foo*. _______________________________________________ Unsubscribe & other changes: http://lists.boost.org/mailman/listinfo.cgi/boost
