If a line of the group file has the wrong number of fields, the pointers f[0], f[1], f[2], and f[3] might point at deadc0de; prior to this revision, the number of fields was checked first and processing halted if it was wrong. I'm busy for the next few days, but if this is still unfixed on Monday I'll take care of it. Colin Percival
