Bug #17253	free(): invalid pointer, mysqld got signal 11
Submitted:	9 Feb 2006 0:32	Modified:	16 Mar 2006 15:03
Reporter:	sanjeev sagar	Email Updates:
Status:	No Feedback	Impact on me:	None
Category:	MySQL Server	Severity:	S1 (Critical)
Version:	5.0.18, 5.0.15	OS:	Linux (Linux 2.4.21-32)
Assigned to:		CPU Architecture:	Any

Description:
Version: '5.0.15-standard-log'  socket: '/tmp/mysql.sock'  port: 3306  MySQL Community Edition - Standard (GPL)
free(): invalid pointer 0xa39f890!
mysqld got signal 11;
This could be because you hit a bug. It is also possible that this binary
or one of the libraries it was linked against is corrupt, improperly built,
or misconfigured. This error can also be caused by malfunctioning hardware.
We will try our best to scrape up some info that will hopefully help diagnose
the problem, but since we have already crashed, something is definitely wrong
and this may fail.

key_buffer_size=1073741824
read_buffer_size=104853504
max_used_connections=7
max_connections=100
threads_connected=6
It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_connections = 3104367 K
bytes of memory
Hope that's ok; if not, decrease some variables in the equation.

Attempting backtrace. You can use the following information to find out
where mysqld died. If you see no messages after this, something went
terribly wrong...

So I removed the top select and run the inner select in the impression that derived table is creating the problem but server crashed for that inner select too. see below

How to repeat:
Run the following queries

Select concat_ws(',',concat_ws(' ',x.nameFirst,x.nameLast),x.Client,x.cells,x.month) Results
from (
Select e.nameFirst, e.nameLast, extract(MONTH FROM t.minDate) month, b.name Client, count(c.id) cells
from Cell c, Plan p, Job j, Employee e, MMTask t, BusinessEntity b
WHERE p.campaignManagerEmployee_id = e.id
AND p.endClient = b.id
  AND p.id = j.plan_id
  AND j.id = c.job_id
  AND t.cell_id = c.id
  AND c.cellType = 3
  AND t.minDate > '2005-12-31'
  AND t.minDate < '2006-02-01'
  group by e.nameFirst, e.nameLast, b.name, extract(MONTH FROM t.minDate))x

or Explain on the same query

Also server crashed for inner select sql too

Suggested fix:
Don't know

Thank you for a problem report. Your 5.0.15 is old enough, so, please, try to repeat on 5.0.18. 

Anyway, the results of SHOW CREATE TABLE for all the tables used (Cell, Plan, Job, Employee, MMTask, and BusinessEntity) are needed. Please, send them.

I've upgraded to 5.0.18 but it still didn't resolve the crash. please see below for messages and stack trace details

No crash. Have you created that tables in 5.0.18 or they left from the previous version of MySQL, 4.x.y? Can you upload some sample data for that tables that gives you the crash?

Please, send also EXPLAIN results for that statement in your environment.
