Description:
Mysql crashes when doing a multi-table update. Only crashes when the update produces results.

How to repeat:
update t1, t2, t3 set t1.a = 1, t2.b = 1 where t1.id = t3.id and t2.id2 = t1.id2

exact query looks something like this

update fleet_data a, deduction b, vendor c
 set a.payable_id = 123
 ,b.reconciliation_id = 123
 where a.payable_id = 0 and a.date >= '2005-11-22' 
 and a.date < '2005-11-23'
 and b.deduction_id = a.deduction_id 
 and c.user_id = b.vendor_id  
 and a.payable_id = 0 
 and if(b.branch_id = 0 , c.branch_id, b.branch_id) = 12345

Hi!

Can you please post the CREATE TABLE statments so that we can execute the queries that you posted ?

Thanks!

I am also experiencing this bug with MySql 5.0.17 on Linux RedHat ES 3. 
Here is the query that crashes the server:

UPDATE vsem.adwords, tmp_rptgoogle SET vsem.adwords.KWID = tmp_rptgoogle.KWID WHERE vsem.adwords.SID=tmp_rptgoogle.SID AND tmp_rptgoogle.KWID != 0;
