------- Comment #1 from pcarlini at suse dot de 2006-03-28 17:38 ------- There is nothing wrong with the current behavior: simply, at the beginning of the file a putback position cannot be made available (i.e., a seek "-1" fails), and, consistently, sungetc() returns traits::eof(), it suffices to check the return value. By the way, the current behavior is totally intended, libstdc++/9439 completely clarified it (useful for some citations from the Standard, but the key point is simply that the unavoidable low level seek fails).
