[BusyBox] Problem with mkdir of busybox-0.60.5 version

[k.s.sathish at delphiauto.com]

Hello all,

I am working with busybox-0.60.5 version and Linux 2.4.18 kernel. At present i
do not have any virtual terminals, i use the serial console debug port on my
hardware platform.

I have used tinylogin-1.2 version to pop up a login session to the users at the
end of booting process.

 I had to make some change to init.c of busybox to route the messages to serial
console. The debug message seen on the serial console is listed below:

$ mkdir /test
mkdir: Segmentation fault

===============================================================================================

When i have to create directory in my home directory i get the above problem. An
 attempt to create a directory in root would give me Segmentation fault.
When i try to give a ps, to see the processes running i dont get to see any
process listing.

Can anyone guide me towards a solution.

Thanks in advance!!!!
