内存释放有异常。当我操作了jieba.Free()。然后开始将一个50M的对象json marshal后存储到file中。程序会报错

-----使用方式

func (jbt *JiebaTokenizer) refreshJieba() {
	if jbt.Jieba != nil {
		jbt.Jieba.Free()
	}

	jbt.Jieba = gojieba.NewJieba()
}

func (t *temp) DownloadParams(paramsFileDownloadPath string) error {
  // xx是我下载的一个很大的对象
	jsonData, err := json.MarshalIndent(xx, "", "  ")
	if err != nil {
		return err
	}

	err = os.WriteFile(paramsFileDownloadPath, jsonData, os.ModePerm)
	if err != nil {
		return err
	}

	return nil
}

你的意思是free后，另一个和gojieba无关的对象操作时就会报错。如果不free的话就不会报错，是么？

[ivory2406]

是的。我就把free先暂时去掉了
