Build Identifier:

Crash during query analysis. Assertion fires.

Reproducible: Always

Steps to Reproduce:

create schema lrbm;

CREATE TABLE lrbm.accident(carid1 integer, carid2 integer, firstMinute integer, lastMinute integer, dir integer, seg integer, pos integer);
CREATE TABLE lrbm.statistics(dir int,seg int,time_minute int,numvehicles int,lav float,toll int,accident int,accidentSeg int);
UPDATE lrbm.statistics
SET toll = 0, accident = 1
SELECT acc.seg
FROM lrbm.accident AS acc
WHERE acc.dir = statistics.dir AND
acc.firstMinute + 1 <= statistics.time_minute AND
acc.lastMinute + 1 >= statistics.time_minute AND
(acc.dir = 0) AND
(acc.seg >= statistics.seg) AND
(acc.seg <= statistics.seg + 4)
(acc.dir <> 0) AND
(acc.seg <= statistics.seg) AND
(acc.seg >= statistics.seg - 4)

Actual Results:

assertion error in
3 0x00007fffe86157bd in rel_join_add_exp (sa=0x134db48, rel=0x1353dc8, e=0x1353f58) at /ufs/mk/current//package/sql/server/rel_select.c:559
