Break Bus Error C


If you register a signal handler using sigaction() and you set SA_SIGINFO, it may be possible to have your program examine the faulting memory address and handle only memory mapped file Top Display posts from previous: All posts1 day7 days2 weeks1 month3 months6 months1 year Sort by AuthorPost timeSubject AscendingDescending Post Reply 3 posts • Page 1 of 1 Return to “ROOT Not the answer you're looking for? After this, the router reloads.

For example, your computer's memory has an address range 0x00 to 0xFF but you try to access a memory element at 0x0100 or greater. You should be able to answer this for yourself with the information found here. Converting a virtual address to a physical address can be a somewhat expensive operation.

Being vulnerable to bus errors is a sign of bad management. Main corresponds to main memory or dynamic RAM (DRAM). SIGSEGV means that you have asked the cpu to do something that is illegal. Bus Error Vs Segmentation Fault The core dump file is named core and is written in whichever directory is current in the process at the time. (On GNU/Hurd systems, you can specify the file name for

SIGBUS can also be caused by any general device fault that the computer detects, though a bus error rarely means that the computer hardware is physically broken—it is normally caused by How To Solve Bus Error In Linux I ran:Code: Select allvalgrind --tool=memcheck --leak-check=yes --show-reachable=yes --num-callers=20 --track-fds=yes --track-origins=yes ./apps/hnureco -c p5.data.kp.q11t --auto -m input/halo_plots.info -n 1000 > output/valgrind_check2 2>&1

Rethink your code if you're having this sort of problem- it's not very performant on X86 to begin with. –Svartalf Dec 16 '14 at 18:31 @Svartalf: On x86, word

Attempting to access a unit larger than a byte at an unaligned address can cause a bus error. Using the show region output, this address falls within the range of "main", or more specifically, "main:heap" or 0x000666B4-0x007FEFFF. And if a system can only deliver a single signal for address problems, SIGBUS would be my choice. Bus Error (core Dumped) Ubuntu Printing the low order bits of the address shows that it is not aligned to a word boundary ("dword" using x86 terminology).
