Re: [HACKERS] Bug on complex join

Hello!

Now for those who said he cannot beleive there is a bug in join - the
following query produced two different results on two different systems
with identical data loaded:

SELECT DISTINCT p.subsec_id
FROM central cn, shops sh, districts d, positions p
WHERE cn.shop_id = sh.shop_id AND sh.distr_id = d.distr_id
AND d.city_id = 2 AND cn.pos_id = p.pos_id
;
subsec_id
---------
1
2
10
11
12
13
14
15
(8 rows)

on one system and

subsec_id
---------
(0 rows)

on the other.

First system is sparc-solrais and second is intel-linux (Debian 2.0,
glibc2). Another glibc2-realted bug?

Oleg.
