I see same here. But it only seems to happen if you compile the rules. I
have one server where I compile the rules, and this exhibited the same
problem.
I can confirm that the endless loop only happens on rule compilation as
well; without compilation everything's fine. Also, because I forgot to
mention it in the last email, I'm running version 3.3.1.
I think I've run into something similar before with re2c and a
completely different rule (maybe in the sought rulesets?; been a long
time). I forget the details however.
I have other servers where I do not compile the rules, and
these run just fine. For now I commented out the rules in 72_active.cf,
and recompiled.
It looks like you can get away with just commenting out the tflags
multiple stanza:
#tflags __PILL_PRICE_1 multiple
Not sure how effective MANY_PILL_PRICE is without the multiple hits from
each sub rule, but figured it'd be useful information. Feeding strings
that hit the rules confirm that _PILL_PRICE_[1-3] all exhibit this
behavior (again, only when using compiled regex'es). Not quite sure how
to compare this current ruleset with the former one (is there a way to
get to the old rulesets?) to see what changed specifically.
At least mailflow is back again :)
Aye. Made for an... exciting early Sunday morning for me, and was a
good lesson in the wisdom of staggering rule updates across servers a
bit better than I was ;)
