andygrove opened a new issue, #3326:
URL: https://github.com/apache/datafusion-comet/issues/3326
## Description
Calling `space(-1)` (or any negative input) through Comet's native execution
causes a crash with:
```
failed to round upto multiple of 64
```
Spark returns an empty string for `space(-1)`.
## Steps to Reproduce
```sql
CREATE TABLE test_space(n int) USING parquet;
INSERT INTO test_space VALUES (-1);
SELECT concat('[', space(n), ']') FROM test_space;
```
## Expected Behavior
Should return `[]` (empty string padded), matching Spark behavior.
## Actual Behavior
Native execution crashes with "failed to round upto multiple of 64".
