- Null pointer of type 'doris::StringRef' in orc reader. The root cause
is error will throw when `num_values == 0` in
`_decode_string_non_dict_encoded_column`.

- Shift exponent 128 is too large for 128-bit type 'ValueCopyType' (aka
'__int128') in parquet reader. The root cause is error will throw when
`len == 0`.
