Segmentation faults occur when accessing memory which does not belong to your process, they are very common and are typically the result http://stackoverflow.com/questions/212466/what-is-a-bus-error of: using a pointer to something that was deallocated. using an uninitialized hence bogus pointer. using a null pointer. overflowing a buffer. PS: To be more precise this is not manipulating the pointer itself that will cause issues, it's accessing the memory it points to (dereferencing). share|improve this answer edited Oct 17 '08 at 15:18 answered Oct 17 '08 at 15:12 bltxd 5,72322336 52 They aren't rare; I'm just at Exercise 9 from How to Learn C the Hard Way and already encountered one... –11684 Mar 26 '13 at 20:12 5 Another cause of bus errors (on Linux anyway) is when the operating system can't back a virtual page with physical memory (e.g. low-memory conditions or out of huge pages when using huge page memory.) Typically mmap (and malloc) just reserve the virtual address space, and the kernel assigns the physical memory on demand (so called soft page faults.) Make a large enough malloc, and then write to enough of it and you'll get a bus error. –Eloff Jul 14 '15 at 0:09 add a comment| up vote 58 down vote A segfault is accessing memory that you're not allowed to access. It's read-only, you don't have permission, etc... A bus error is trying to access memory that can't possibly be there. You've used an address that's meaningless to the system, or the wrong kind of address for that operation. share|improve this answer answered Oct 17 '08 at 14:55 Clinton Pierce 6,91894576 add a commen

When I Su, and try again, it asks me for RSA authenticatin. I say yes, and then it hangs trying to connect - I assume it's tryign to connect.The I get frustrated, I close the terminal, and I try again in su mode. It just hangs at that point.Anyone know how to fix this?

Is this the stock ssh client that comes with OS X, or have you installed a different one via something like Fink or MacPorts? You could run some debugging from ssh to see where things are hanging up. From your client, you could use the -v option which will give your some debugging information and may tell you who is hanging up. If that doesn't tell you anything, you can do some similar things on the remote side to the sshd daemon that is accepting your connection.However, I'm still concerned about the bus error. Can you paste your connection attempt here, showing that error?
