[GitHub] [arrow-datafusion] alamb opened a new issue, #7118: Panic: `index out of bounds: the len is 0 but the index is 0` in `first_value` / `last_value` when used as an aggregate

URL: https://github.com/apache/arrow-datafusion/issues/7118

   ### Describe the bug
   
   Panic: `index out of bounds: the len is 0 but the index is 0` in `first_value` / `last_value` when used as an aggregate
   
   ### To Reproduce
   
   ```sql
   create table foo (x int) as values (1), (2);
   select last_value(x) from foo;
   ```
   
   Result:
   
   ```shell
   (arrow_dev) alamb@MacBook-Pro-8:~/Software/influxdb_iox2$ datafusion-cli
   DataFusion CLI v28.0.0
   ❯ create table foo (x int) as values (1), (2);
   0 rows in set. Query took 0.003 seconds.
   ❯ select last_value(x) from foo;
   thread 'main' panicked at 'index out of bounds: the len is 0 but the index is 0', /Users/alamb/Software/arrow-datafusion/datafusion/physical-expr/src/aggregate/first_last.rs:374:13
   note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace
   ```
   
   These other queries panic:
   
   ```
   0 rows in set. Query took 0.003 seconds.
   ❯ select last_value(x) from foo GROUP BY x;
