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 :)
