Description:
The following query sequence crashes the server:

How to repeat:
drop table if exists t1, t2;                                                        
create table t1(a int primary key, b varchar(30)) ENGINE = BDB;

delete from t1 ;                                                                
insert into t1 values (1,'one');                                                
insert into t1 values (2,'two');                                                
insert into t1 values (3,'three');                                              
insert into t1 values (4,'four');                                               
commit ;                                                                        

    
set @duplicate='duplicate ' ;
set @1000=1000 ;
set @5=5 ;
set @float=1.00;
set @five='five' ;
create table t2 like t1 ;
insert into t2 (b,a) 
select @duplicate, sum(first.a) from t1 first, t1 second
  where first.a <> @5 and second.b = first.b
     and second.b <> @five
  group by second.b
  having sum(second.a) > @2
union
select b, a + @100 from t1
  where (a,b) in ( select sqrt(a+@1)+CAST(@float AS signed),b 
                 from t1);

Suggested fix:
n/a

Another test case:

drop table if exists t1, t2;
create table t1(a int primary key, b varchar(30)) ENGINE = BDB;
insert into t1 values (1,'one');
insert into t1 values (2,'two');
insert into t1 values (3,'three');
insert into t1 values (4,'four');
create table t2 like t1;

insert into t2 (a, b) 
  select a, b from t1 where (a,b) in ( select a,b from t1);
