[GitHub] [arrow-rs] jhorstmann opened a new issue, #1601: ListArray::from(ArrayData) dereferences invalid pointer when offsets are empty

[GitBox <gi...@apache.org>]

jhorstmann opened a new issue, #1601:
URL: https://github.com/apache/arrow-rs/issues/1601

   **Describe the bug**
   
   `ListArray::from(ArrayData)` tries to validate that the first offset is zero, without checking that the offset buffer actually contains any data. This leads to a segmentation fault when creating an empty ListArray.
   
   Additionally this validation should not really be needed, starting from a non-zero offset should work fine.
   
   **To Reproduce**
   Create an `ArrayData` object with list type and an empty offset buffer.
   
   **Expected behavior**
   The ListArray creation should succeed, resulting in an empty array.
   
   **Additional context**
   Add any other context about the problem here.
