When reading a JSON object with duplicate keys, Arrow can crash if the duplicate key was not in schema. In this case, the absent_fields_stack_ will not have an index to represent the duplicated key. When we encounter the duplicated key for a second time, field_index_ will be non-negative and greater than the size of absent_fields_stack_, thus triggering a crash when we attempt to read from absent_fields_stack_. -- This is an automated message from the Apache Git Service.
