Segmentation faults occur when accessing memory which does not belong to your process, they are very common and are typically the result 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 5,75322336 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 6 Another cause of bus errors (on Linux anyway) is when the op

One way is misaligned access and I have tried the examples given here and here, but no error for me - the programs execute just fine. Is there some situation which is sure to produce a bus error? c++ bus-error share|improve this question edited Jan 15 '10 at 9:50 asked Jan 15 '10 at 4:06 Lazer 25.2k66212310 2 What platform and hardware architecture are you using? http://stackoverflow.com/questions/2069450/how-to-get-a-bus-error –R Samuel Klatchko Jan 15 '10 at 5:32 it should be noted that by default x86 will not have a bus error, instead it will work but the memory access will be not as performant as an aligned read. on the other hand SPARC arches do have a bus error. –Evan Teran Jan 15 '10 at 6:50 1 No, see Michael Burr's comments and my answer. Even on x86, you can get a bus error by attempting to access memory which does not exist (as opposed to a segmentation fault, which comes from a violation of access policy). –ephemient Jan 16 '10 at 16:29 add a comment| 11 Answers 11 active oldest votes up vote 11 down vote accepted Bus errors can only be invoked on hardware platforms that: Require aligned access, and Don't compensate for an unaligned access by performing two aligned accesses and combining the results. You probably do not have access to such a system. share|improve this answer answered Jan 15 '10 at 4:09 Ignacio Vazquez-Abrams 447k64800956 is there some way to be sure of that? –Lazer Jan 15 '10 at 4:11 @eSKay: If you're using an Intel CPU, which means basically any personal computer nowadays, you will never get a bus error
