The purpose of the tool is to access/configure a PCI-express cards that has some firmware running on it. I made some slight change to code,nothing significant and suddenly got a "Bus error". I know that is is caused by unaligned memory access, but in the above context is it more likely

to be in the firmware memory, i.e a firmware read across the PCI-express bus. I certainly don't believe that my small software change could have caused the "Bus error". Another surprising fact is that a different version of software is working well with this firmware. Can anyone throw some light on the issue. linux debugging bus share|improve this question edited May 3 '11 at 13:44 skaffman 276k62614652 asked May 3 '11 at 13:40 liv2hak 3,8391659106 closed as off-topic by Ciro Santilli 烏坎事件2016六四事件 法轮功, Yu Hao, Chris Loonam, John Pirie, Rob Aug 7 '15 at 16:35 This question appears to be off-topic.

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 5,70322336 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)
