How To Debug Bus Error
vote accepted Bus errors are rare nowadays on x86 and occur when your processor cannot even attempt the memory access requested, typically: using a processor instruction with an address that does not satisfy its alignment requirements. 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) 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.)

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, http://stackoverflow.com/questions/5870353/bus-error-system-error 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.

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? Helpful (0) Reply options Link to this post by lazyrussian, lazyrussian Jun 6, 2008 10:28 AM in r

The following errors are actual screen shots from a Terminal window on two different Mac systems: Example: 1 (user is able to launch idl but receives the error as soon as the plot command is used.)
