Description:
First of the this issue is on a Dual AMD64 Suse 9.1 machine.
I am trying to create two identical tables each in it's own database. Then I create a third database into which is created a view of a (select * one.a) union (select * two.a).
Next I want to query the new view with a 'select * from three.a' (my new view).
The First time it returns the results successfully.
The Second time with the same query FAILS and the Server restarts.
The Third time with the same query returns the results successfully.
The Forth time again same query FAILS and the Server restarts....etc...
I have tried the prepared MySQL binaries 5.0.16 for AMD64, and I have built my own from source for 5.0.16 and have the exact same failure. When I built my own from source I included the --with-debug=full.
What can I do? I'm stumped at this point.
I have tried this on Red Hat 9, and it works fine with 5.0.15.
How to repeat:
mysql> create database one
mysql> create table one.a (col1 int(4), col2 varchar(8));
mysql> insert into one.a (col1,col2) values (1,'test');
mysql> create database two;
mysql> create table two.a (col1 int(4), col2 varchar(8));
mysql> insert into two.a (col1,col2) values (1,'test');
mysql> create database three;
mysql> use three
mysql> create view three.a as (select *, 'one' from one.a) union (select *, 'two' from two.a);
mysql> select * from three.a;

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,

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.
