Changhee,
You code is trying to access a memory location that is protected by the
kernel (0x30) that is why you are getting a SIGSEGV. This problem
usually is a result of over running the space allocated by an array. In
this case it looks like you have overrun an array and written the value
48 into a pointer. This problem just never bit you on the Sun but it is
still a coding error.
