Yes, it's true. insert() and erase() invalidate all existing iterators into a std::vector. Why not try std::map<lyx::size_type, lyx::size_type> rowSignature; which I'd imagine will actually be easier to use than your vector in this regard and will remove the "implicit connection" that Lars is worried about. -- Angus
