  • 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.

It's very platform specific as to what causes a bus error (or even exactly what constitutes a bus error). –Michael Burr Jan 15 '10 at 6:23 | show 7 more comments 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.
