Обсуждение: Postgresql 8.2.4 crash with tsearch2

hi,
I have compiled postgresql 8.2.4 on a debian etch witch french snowball
stemmer .
I applied the lastest patch send by Teodor Sigaev
(http://www.sai.msu.su/~megera/postgres/gist/tsearch/V2/tsearch_snowball_82-20070504.gz)

and my backend still crash.
I tested on 2 differents server both with etch, one with i386 the other
with amd64.
The first crash on ts_vector when the parameter string is longer than
200 characters.
The second crash on lexize
If you have other patch to try I will do it :)

If for you there is no bug, I don't understand what's appen to my
servers. any idea ?

thank

Regards

hi,
Ok it's my mistake, I forgot to add "-i" at for gendict config.sh


regards
