help stomp out a Mosaic bug under Ultrix 4.2...

There seems to be a nasty li'l bug somewhere inside either Mosaic or
Motif that is causing an occasional coredump when closing a window,
but only on Ultrix boxes (and then only on some Ultrix boxes -- I
absolutely cannot reproduce it on our Ultrix box). The traceback
looks like this:

> 0 abort.abort(0x84d82, 0x2b9612ee, 0x84d82, 0x2b9612ee, 0x4003b4)
["../fprintf.c":25, 0x5442ec]
1 RealFatal() ["main.c":64, 0x4002cc]
2 FatalProblem(sig = 10, code = 16, scp = 0x7fffa984, addr =
0x4002e8 = "\350\377\275'^T") ["main.c":79, 0x4003b0]
3 _draw(0x2400114, 0x1013ddac, 0x7fffb030, 0x1010b158, 0x5)
["XmString.c":3470, 0x43732c]
4 _XmStringDrawImage(0x1, 0x100132e0, 0x4feaf0, 0x1010b158, 0x5)
["XmString.c":3583, 0x4376d4]
5 DrawList(0x0, 0x1, 0x1, 0x0, 0x0) ["List.c":2016, 0x44ab10]
6 XmListDeleteItemsPos(0x46064c, 0x2, 0x22, 0x0, 0x40727c)
["List.c":5851, 0x451c68]
7 mo_kill_node_descendents(win = 0x100926c8, node = 0x100d9778)
["history.c":79, 0x40a384]
8 mo_delete_window(win = 0x100926c8) ["gui.c":3331, 0x407278]
9 menubar_cb(w = 0x100cefa0, client_data = 0x10009 = "", call_data =
0x7fffafb0 = "\n") ["gui.c":2211, 0x405740]
...

If this happens to you, can you send me the values of count and
node->position in mo_kill_node_descendents()? Also let me know if the
window history dialog was open for the window being closed at the
time.

Thanks much,
Marc
