24.5; strange behavior by line-height property |

(let ((buf (get-buffer-create "*Test*"))
(newline (propertize "\n" 'line-height t)))
(set-buffer buf)
(dotimes (i 1000)
(insert (format "%9d" i) newline))
(switch-to-buffer buf))
Evaluating this form, I expect the window displays numbers near 999
and the cursor is displayed at the end of the buffer.
But the window displays numbers from 864 to 896
and the cursor is displayed after 864.
Althouth texts are displayed after the cursor,
C-x C-= shows "point=10001 of 10000 (EOB) column=0".
Also point motion commands work strangely in the buffer.
M-v moves cursor from after 864 to before 415,
from before 415 to before 16.
C-v signals "End of buffer" even if the cursor is at the beginning of
the buffer.
M-> moves the cursor before 581.
Typing many C-n to scroll the window from before 581,
the cursor jumps to after 461.
Then typing more C-n, the window scrolls by one line for each input.

This was a 12-year old bug, now fixed on master.
Thanks.
