[BusyBox] Busybox SH signal handling

Hello,

Has anyone looked into adding signal-related error handling to the
Busybox shell? IE:

bryan at squirt:~/src$ ./segtest
Segmentation fault
bryan at squirt:~/src$

in bash. but in busybox sh:

bryan at squirt:~/src$ busybox/busybox sh


BusyBox v0.48pre (2000.11.28-20:59+0000) Built-in shell
Enter 'help' for a list of built-in commands.

/home/bryan/src # ./segtest
/home/bryan/src # 

No error message from Busybox shell.

(segtest just performs an invalid pointer dereference).

How difficult would it be to have the busybox shell output "Segmentation
fault" on SIGSEGV, and possibly
intercept other fatal signals?

If noone has looked into this, I will give it a shot when I get some
time.

Thanks,

Bryan
