It seems I can always reproduce this -- at least to get a stack trace
identical to the one reported.

This is tmux cvs HEAD (as of today) on Linux (Debian Unstable).

If I start tmux like this:

$ tmux -Lrandom -f /dev/null

... and then immediately start to split the window, creating random
horizontal/vertical splits -- do it a few times until you get four of five.

Then turn on "mouse-select-pane":

:set mouse-select-pane

... then click to any random pane with the mouse to make it active, and
press:

^d

... to close the pane.  I immediately then get a "[lost server]" error, and
a coredump.  Here's the results:

(gdb) bt
#0  0x080839fc in window_pane_visible (wp=0x9011570) at window.c:836

    at client.c:153
#7  0x080770f4 in main (argc=0, argv=0xbfbd1390) at tmux.c:495

Doing some digging:

(gdb) p wp->xoff
$2 = 1963065346
(gdb) p w->sx
Cannot access memory at address 0x2000264
(gdb) p w
$3 = (struct window *) 0x2000200
(gdb) p *w
Cannot access memory at address 0x2000200

What's up with the struct window * here?

Also -- things get a little more interesting...

If I repeat the above steps, but this time keep splitting a window down so I
get a really tiny pane, and type "ls" (so that wp->fd > -1) -- and then
close it -- again with "^d", tmux goes round in an infinite loop, with the
title of the window.  This is due to automatic-rename for sure -- the title
of the window goes through endless loops of:

0:z [dead]
0:X [dead]

... over and over.  There's always a random character before [dead] -- no
tmux crash, but it does look like (through stracing it) it's caught around
here:

names.c:window_name_callback():

if (w->active->cmd != NULL && *w->active->cmd == '\0' &&
    name != NULL && name[0] == '-' && name[1] != '\0')
        wname = parse_window_name(name + 1);

I'm having problems tracking this down to be honest.
