[GitHub] [arrow] spenczar commented on issue #35692: Null fixed-length lists cannot be read from parquet file

   Agreed, this section looks a little off to me:
   https://github.com/apache/arrow/blob/8a856c90f9b8fa33de636f98eb33123ccc304b25/cpp/src/parquet/arrow/reader.cc#L676-L682
   
   The offset difference `size` _should_ be zero for null values. I think that code needs to be checking the validity buffer.
