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 5,68322336 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 55 down vote A segfault is accessing memory that you're not allowed to access.

perform I/O to a device that is restricted or that does not exist. http://stackoverflow.com/questions/212466/what-is-a-bus-error This message is usually accompanied by a core dump, except on read-only file systems. Action Use a debugger to examine the core file and determine what program https://docs.oracle.com/cd/E19455-01/806-1075/msgs-1097/index.html fault or system problem led to the bus error. If possible, check the program's output files for data corruption that might have occurred before the bus error. Technical Notes Bus errors can result from either a programming error or device corruption on your system. Some common causes of bus errors are: invalid file descriptors, unreasonable I/O requests, bad memory allocation, misaligned data structures, compiler bugs, and corrupt boot blocks.

From GUII try to start an application (it might be that this http://www.cplusplus.com/forum/unices/123704/ only concerns gtk applications such as evince & gthumb but I don't know). The application does not start, instead I am told by my GUI (e17) 'XXXX (the application) stopped running unexpectedly. There was no error message. This error log will be saved as /home/...'. This error message matches the various joke error messages concocted by bus error Microsoft in unhelpfulness. The log is not saved.From TerminalI try to start it from the terminal. The terminal tells me 'Bus error (core dumped)'. Nothing more. I could not find any coredump - though the journalctl log does at least know about this: "May 09 02:03:07 xxxxxx systemd-coredump[9439]: Process 9436 (XXXX) dumped core." Running the application with strace is also not very helpful, though it hints that it all has to bus error core do with dconf: "open("/etc/dconf/profile/user", O_RDONLY) = -1 ENOENT (No such file or directory) (...) open("/home/xxxxx/.config/dconf/user", O_RDONLY) = 11"Google searches etc.Not helpful. But then again: who is going to talk about google any more in just a couple of years.Solutionremove /home/
