IMHO, conceptually I think this is more of a STL bug than a compiler one. In the special case that the size of elements is zero, std::vector should just use the max size_type value for max_size(). All allocations will be zero-sized, and as actually the maximum allocatable vector would have infinite elements, the maximum index value is rather restricted by the maximum number that can be encoded in size_type. For many cases (specially template programming) I don't want empty structs without virtual functions to use any space. Regards, Juan Jesus.
