[jira] [Commented] (PARQUET-1169) [C++] Segment fault when using NextBatch of parquet::arrow::ColumnReader in parquet-cpp

Hatem Helal commented on PARQUET-1169:
--------------------------------------

[~frankfang], could you try this again using arrow master?  I think this might have been resolved by ARROW-5608.
