Hi Tarun ,
Thank you for the reply and the question here is ,The unaligned access is
the bus error .Hence OS should be signaled SIGBUS.Because the SIGILL is
mislead the end user(developer).
Wiki answer
On POSIX <http://en.wikipedia.org/wiki/POSIX>-compliant
platforms, *SIGBUS* is the
signal<http://en.wikipedia.org/wiki/Signal_(computing)> sent
to a process <http://en.wikipedia.org/wiki/Process_(computing)> when it
causes a bus error <http://en.wikipedia.org/wiki/Bus_error>.
