I can't think of anything else obvious between 7.0 & 7.1 that would affect this (particularly since I have an re that works fine in 7.1 - at least a 7.1 from, say, September). As far as bisecting goes, I recommend binary search by date on the RELENG_7 branch rather than trying to rollback individual revs. Note that cvs 1.12 allows checking out by date (-D) on a branch (-rRELENG_7) (but not 1.11). Or you can use cvsup to help with that I think.
