[GitHub] [arrow-rs] tustvold opened a new issue, #3671: FFI Fails to Account For Offsets

tustvold opened a new issue, #3671:
URL: https://github.com/apache/arrow-rs/issues/3671

   **Describe the bug**
   <!--
   A clear and concise description of what the bug is.
   -->
   
   Passing an `ffi::ArrowArray` with a non-zero offset, results in an `ArrayData` with `Buffer` with truncated lengths, as it assumes they have no offset when recording their length.
   
   This is the cause of #3646
   
   **To Reproduce**
   <!--
   Steps to reproduce the behavior:
   -->
   
   **Expected behavior**
   <!--
   A clear and concise description of what you expected to happen.
   -->
   
   Sliced arrays should round-trip through FFI
   
   **Additional context**
   <!--
   Add any other context about the problem here.
   -->
   
   I don't think this can result in UB, it just results in bounds checks failing when they shouldn't
