[jira] [Created] (ARROW-10852) [C++] AssertTablesEqual(verbose=true) segfaults if the left array is longer

Ben Kietzman created ARROW-10852:
------------------------------------

             Summary: [C++] AssertTablesEqual(verbose=true) segfaults if the left array is longer
                 Key: ARROW-10852
                 URL: https://issues.apache.org/jira/browse/ARROW-10852
             Project: Apache Arrow
          Issue Type: Bug
          Components: C++
    Affects Versions: 2.0.0
            Reporter: Ben Kietzman
             Fix For: 3.0.0


{{MultipleChunkIterator}} is used to implement the verbose comparison in AssertTablesEqual and seems to assume that the arrays have identical length. If the left chunkedarray is longer, this will result in segfaulting when trying to read nonexistent chunks of the right chunkedarray.
