Segmentation fault occurs when you try to access a memory which doesn't
belong to your program.
You are trying to cast a memory location of one byte to 4 byte(assuming
size of long int to be 4). It is possible that other three bytes belong to
some other process.
That is why you are getting segmentation error.
Correct me if m wrong.
