I've produced a more informational backtrace by compiling it from source
and trying again. The problem occurs when one has activated the option
allow_numbers: true
and tried to run 'htfuzzy soundex' on the database files. As numbers
from a string are being skipped in Soundex::generateKey(), a segfault
occurs as the char *word is being increased by
while (!isalpha(*word))
word++;
if the given word contains numbers only (or: contains only nonalpha
chars, to be precise).
The attached diff[1] fixes this problem for me, it's a diff against
htdig 3.1.6, file htdig-3.1.6/htfuzzy/Soundex.cc
