The writev() function shall always write a complete area before proceeding to the next." and I imagine that is what LTP is attempting to test. The moment you pass an invalid address you are in the land of undefined behaviour, so I would read the standard as actually trying to deal with the behaviour in defined situations (eg out of disk space mid writev()).
