Bus Error 10 C

Accordingly, the CPU sets this physical address on its address bus and requests all other hardware connected to the CPU to respond with the results, if they answer for this specific The disk backup will also occur more quickly since it doesn't have to go over the network to your directory. Could the atmosphere be compressed and put into bottles? I suspect it might have to do with memory or overflowing the buffer, but that's completely unscientific and a gut feeling. http://alltechgossip.com/bus-error/bus-error-c.html

Unlike bytes, larger units can span two aligned addresses and would thus require more than one fetch on the data bus. What's the fastest way to generate a 1 GB file containing only random numbers? For example, for hardware based on the IBM System/360 mainframe, including the IBM System z, Fujitsu B8000, RCA Spectra, and UNIVAC Series 90, instructions must be on a 16-bit boundary, that How do you combine the elements in Sheldon's T-shirt?

sptr = (short *)(((char *)sptr) + 1); *sptr = 100; */ return 0; } Compiling and running the example on a POSIX compliant OS on x86 demonstrates the error: $ gcc Is the Joker Based on anything? For example, if multi-byte accesses must be 16 bit-aligned, addresses (given in bytes) at 0, 2, 4, 6, and so on would be considered aligned and therefore accessible, while addresses 1, share|improve this answer edited Dec 17 '14 at 8:36 answered Oct 17 '08 at 14:58 unwind 258k39338464 1 In case, I had data[8]; This is now a multiple of 4

  • I am going to try this once I get my program working the current way I have it.
  • Could it be caused by [lack of] disk space?
  • Even if line had a longer lifetime, it wouldn't be useful to have all your array elements having the same pointer (they'd each just point to whatever happened to be written
  • Thanks!
  • The goal in my game is to take a huge 5049 x 1 text file of words.
  • Here is a program that, I think, will compile with every C or C++ compiler, but should cause a bus error when the second printf is attempted...
  • It looks like you are learning C.
  • Another possible cause is an alignment error.

Look carefully at the code above. A function taking no arguments should be declared as void in C. share|improve this answer answered Oct 17 '08 at 14:57 Mark Baker 3,66211823 1 My i7 certainly has an MMU, but I still came across this error while learning C on How To Solve Bus Error In Linux It's bad practices, to be blunt. :D –Svartalf Apr 23 '15 at 18:15 | show 2 more comments up vote 2 down vote It depends on your OS, CPU, Compiler, and

On POSIX-compliant platforms, bus errors usually result in the SIGBUS signal being sent to the process that caused the error. Bus Error Vs Segmentation Fault Will it cause mis-alignment errors on a fragile architecture.

This is a buffer overflow, which can lead to Bad Things if you clobber something important. Bus Error (core Dumped) C Apr 19 '11 at 13:42 Thanks for the detailed description. You've used an address that's meaningless to the system, or the wrong kind of address for that operation.

To allow core dumps and still not have quota worries, you can make a symbolic link from the name core into the /tmp directory.

Finally, you're trying to copy the strings using =. This is an example of register indirect addressing. Example[edit] This is an example of unaligned memory access, written in the C programming language with AT&T assembly syntax. #include int main(int argc, char **argv) { int *iptr; char *cptr; A skill you need to master early is basic debugger use.

The mmap spec says that: References within the address range starting at pa and continuing for len bytes to whole pages following the end of an object shall result in delivery I feel this may indeed be a better solution. –GeekyOmega Jul 30 '12 at 19:45 add a comment| Your Answer draft saved draft discarded Sign up or log in Sign Unsourced material may be challenged and removed.

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 This error is caught after the attempted conversion of the virtual address to a physical address. Most CPUs can access individual bytes from each memory address, but they generally cannot access larger units (16 bits, 32 bits, 64 bits and so on) without these units being "aligned" If you're not interested in debugging the program yourself, you can skip the rest of this section.
