> The following sequence of statements crashes sqlci. The last SELECT … UPDATE
> statement returns a bunch of warnings before the executor asserts with a core
> file, as shown in the following example:
> >>set schema seabase.mytest;
> --- SQL operation complete.
> >>create table t (a int, b char(9), c int);
> --- SQL operation complete.
> >>create index t_idx on t(a, b);
> --- SQL operation complete.
> >>insert into t values (3, 'a', 2), (1, 'b', 3), (4, 'c', 1), (2, 'd', 4),
> >>(2, '
> b', 5), (2, 'c', 3), (1, 'c', 2), (1, 'a', 4);
> --- 8 row(s) inserted.
> >>select * from (update t set c = 100 where a < 3) as x order by x.a;
