> [https://github.com/apache/orc/issues/1021.]
> h3. What changes were done as Improvement.
> The changes are made to validate the indices in the Protobuf message type
> tree especially for the Type_Kind_STRUCT when fieldnames are less than the
> subtypes_size() , so it won't crash when we convert the proto::Types to
> TypeImpls.
