but i am still struck in the same problem.

Bus Error (Core Dumped):

I was checking the size of the stack space allocated to a process. For that i used recursion and I got Seg fault after almost 8 MB(7.98 MB) of data pushed on to the stack.

Then I increased the size of Stack to 256 MB  (using system call setrlimit()) now i am getting an error i.e Bus error (core dumped)…

I googled for this error but still i am not getting what actually caused this???

How is this different from Segmentation fault????
