> Calling {{parquet::arrow::FromParquetSchema}} when reading the corrupt file attached to PARQUET-1481 results in a SEGV. I'm not sure when this was introduced but I didn't observe this problem with our app that uses parquet-cpp v1.4.0. Our team caught this while integrating Arrow 0.12.1 into MATLAB.
> To reproduce this, add the following lines to [parquet-reader.cc|https://github.com/apache/arrow/blob/master/cpp/tools/parquet/parquet-reader.cc#L66], build, and try to read the corrupt file attached to PARQUET-1481.
> {code:java}
> const auto parquet_schema = reader->metadata()->schema();
> std::shared_ptr<::arrow::Schema> arrow_schema;
> PARQUET_THROW_NOT_OK(parquet::arrow::FromParquetSchema(parquet_schema, &arrow_schema));{code}
