: My guess was the first obvious one I could think of since I knew
: changes happened in the re/rl drivers. 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.
I also think there were some bugs fixed in re/rl in stable lately...
