Go: thrift compiler generates wrong code for list of aliased type

typedef i8 StatType

struct SomeStruct {
 1: list<StatType> stats;
}

func (p *CSVAnalyzeTaskPayload)  ReadField1(iprot thrift.TProtocol) error {
  _, size, err := iprot.ReadListBegin()
  if err != nil {
    return thrift.PrependError("error reading list begin: ", err)
  }
  tSlice := make([]StatType, 0, size)
  p.Stats =  tSlice
  for i := 0; i < size; i ++ {
var _elem1 int8
    if v, err := iprot.ReadByte(); err != nil {
    return thrift.PrependError("error reading field 0: ", err)
} else {
    temp := int8(v)
    _elem1 = temp
}
    p.Stats = append(p.Stats, _elem1)
  }
  if err := iprot.ReadListEnd(); err != nil {
    return thrift.PrependError("error reading list end: ", err)
  }
  return nil
}
