I think I am able to trigger it using the query below:
```sql
CREATE EXTERNAL TABLE decimal_simple (
c1 DECIMAL(10,6) NOT NULL,
c2 DOUBLE NOT NULL,
c3 BIGINT NOT NULL,
c4 BOOLEAN NOT NULL,
c5 DECIMAL(12,7) NOT NULL
)
STORED AS CSV
WITH HEADER ROW
LOCATION '../datafusion/core/tests/decimal_data.csv';
select * from decimal_simple where c1 >= 0.00004 order by c1 limit 100;
```
But still not sure about the underlying issue.
The size of the input array changes even though the contents stay the same
(so probably buffers too). Maybe that assumption doesn't hold when we are
recreating the arrays (and/or maybe the ordering actually changes how buffers
are built), so instead of triggering an assertion, we might need to factor this
case in and just run into this branch when we are sure that the `new_size` is
less than `size`.
