What if the fault handler does a fault ( like seg fault in seg fault handler
) , cause in i386, i remember such a situation causes a processor reboot as
it becomes a infinite loop !

the same code works fine on an iPAQ ! without any problems
and i did a diff of the strace output on iPAQ and GCP and found that the
following lines are extra in case of iPAQ while GCP reboots before it can
print the lines !
brk(0xc8000) = 0xc8000
close(4) = 0
close(3) = 0
munmap(0x40000000, 4096) = 0
_exit(0) = ?

so i conclude that the system crashes in brk() sys call !

If you can point out the cases where the kernel reboots without showing any
message , then it will be easier to debug for me!
and thanks a lot for the reply :)
