> I've observed occasional crashes when using the {{parquet::arrow::ColumnReader}} to iteratively read a fixed number of records. This has been quite tricky to isolate but compiling the attached version of parquet-arrow-example with ASAN has pointed me to an out-of-bounds access at [cpp/src/parquet/arrow/record_reader.cc#L356|https://github.com/apache/arrow/blob/master/cpp/src/parquet/arrow/record_reader.cc#L356]
