Others seem unable to reproduce also, but for me it is 100%
reproducible.
So trying to put every info:
$ xwininfo
xwininfo: Please select the window about which you
would like information by clicking the
mouse in that window.
xwininfo: Window id: 0x60000d "xterm"
Absolute upper-left X: 3
Absolute upper-left Y: 24
Relative upper-left X: 0
Relative upper-left Y: 21
Width: 884
Height: 556
Depth: 16
Visual: 0x21
Visual Class: TrueColor
Border width: 0
Class: InputOutput
Colormap: 0x20 (installed)
Bit Gravity State: NorthWestGravity
Window Gravity State: NorthWestGravity
Backing Store State: NotUseful
Save Under State: no
Map State: IsViewable
Override Redirect State: no
Corners: +3+24 -713+24 -713-320 +3-320
-geometry 80x24+1+1
(Note: the position has nothing to do with, the geometry has).
vi: set ts=8
A vis version of the one line
$ vis -w
\011\011v_stack[nval].ival\040=\040v_stack[nval-1].ival\040+\040v_stack[nval-1].len\011\012
Suspicious thing: when it crashes with ts=8, the last char displayed
just against the right border of the window (the remaining of the line
is not wrapped; it is simply not displayed) is the 'l' of the third
"nval". Then there are exactly 8 chars after before new line, the
last one being a tab (a tab and 8; and the width is 80)...
How to reproduce: in vi(1), use '$' to go to the end of the line.
Other way to reproduce for me. Set ts=4, move to the end of the line,
and then set ts=8.
The locales:
$ locale
LANG="POSIX"
LC_CTYPE="fr_FR.ISO8859-15"
LC_COLLATE="POSIX"
LC_TIME="POSIX"
LC_NUMERIC="POSIX"
LC_MONETARY="POSIX"
LC_MESSAGES="fr_FR.ISO8859-15"
LC_ALL=""
and finally the window manager is twm (all are from NetBSD X11; not
pkgsrc).
