#38347) Csv reader parse data incorrect when data enclosing line_delimiter, for example, line_delimiter is \n and enclose is ', data as follows: ``` 'aaaaaaaaaaaa bbbb' ``` it will be parsed as two columns: `'aaaaaaaaaaaa` and `bbbb',` rather than one column ``` 'aaaaaaaaaaaa bbbb' ``` The reason why this happened is csv reader will not reset result when not match enclose in this `output_buf_read`, causing incorrect truncation was made.
