Summary:                    vi crashes often
Description: 
I have been using BusyBox since version 0.6 and I have always noticed that
'vi' will crash while editing a file.  One of the guys I work with has
found a way to reproduce the crash every time.

Load VI on either a new file or a previously created one and then pres the
following keys:

iThis is a test.<ESC>7<Left>i<C-BS><C-BS>was<ESC>7<Left>x

Once you have pressed 'x' busybox will enter a system where it is causing
a Memory dump over and over until you login on another session and kil the
vi process.  

This problem was seen using kernel 2.4.20 (if that is of any importance)

We also saw the same problem while running with Linux kernel 2.6

Cannot reproduce this on 1.1.0-pre1 under Ubuntu.

This occurs on a bigendian box

Processor: ARM IXP1200

If needed I can attach the config we use when compiling busybox.

We are running Busybox 1.01 and we downloaded this version ran it on Ubuntu
and found that it works.  So perhaps itis releated to the Big Endian or
Processor we are using.

Ah, now that's quite possible.  I haven't personally got an arm system to
test it under, but I can try to scrounge up an arm distro to run under
qemu.  Won't be this week though.

Erik Andersen is really the vi maintainer and the guy with arm hardware. 
Emailing him directly might work here...
