----------------------------------

             Summary: [C++] StringArray/BinaryArray comparisons may be 
incorrect when values with non-zero length are null
                 Key: ARROW-537
                 URL: https://issues.apache.org/jira/browse/ARROW-537
             Project: Apache Arrow
          Issue Type: Bug
          Components: C++
            Reporter: Wes McKinney


see code review comments in https://github.com/apache/arrow/pull/322

because we compare the entire data range without regards to nullness, this may 
compare null data segments which should be ignored
