Hi,
I'm having problems with htfuzzy which suddently started segfaulting and
did not yet stop doing so. A small shell script started by cron runs the
following commands in this order:
htdig -i -s -c $CONF
nice -20 htmerge -v -s -c $CONF
htfuzzy -v endings -c $CONF
htfuzzy -v soundex -c $CONF
htfuzzy -v metaphone -c CONF
htfuzzy -v accents -c $CONF
htfuzzy soundex then segfaults. I ran it with strace:
$ strace htfuzzy -v soundex -c /etc/htdig/htdig.conf
