OK, thanks for testing.  I'm therefore closing the bug report.

Hi,

When display-line-numbers-mode is on and the (point) is on the
beginning of line, posn-at-point returns a wrong value.

Reproducible in emacs -Q:

```
(save-excursion
  (message "Without display-line-numbers:")
  (display-line-numbers-mode -1)
  (goto-char (line-beginning-position))
  (message "column 0: %s" (car (nth 2 (posn-at-point))))
  (forward-char)
  (message "column 1: %s" (car (nth 2 (posn-at-point))))
  (message "With display-line-numbers:")
  (display-line-numbers-mode)
  (goto-char (line-beginning-position))
  (message "column 0: %s" (car (nth 2 (posn-at-point))))
  (forward-char)
  (message "column 1: %s" (car (nth 2 (posn-at-point))))
  )
```

Output:
```
Without display-line-numbers:
column 0: 0
column 1: 19
With display-line-numbers:
column 0: 0
column 1: 114
```

On the bol, it returns zero but it should return (- 114 19)
