Bus Error C Programming


The problem with this is that array[x] doesn't belong to the array, the array only has useable indices of 0 to (x - 1). But in that case, would it compile correctly? Still to me these errors have slightly different meanings, although I must admit that this is based mostly on C programming in an HP-UX environment. You just simply don't want to DO this.

I get the feeling that you are actually running your program, that the error is seperate from the compilation process, and that it stems from you not checking the return values Trying to access an undefined virtual memory address is generally considered to be a segmentation fault rather than a bus error, though if the MMU is separate, the processor can't tell when u move past the end of the file, buf still at a valid mapped address, you get a bus error.

  1. Then, you have the ability to run your program after this happens.
  2. Look carefully at the code above.
  3. you allocate the array to hold 5049 pointers, but you simply read however much is in the file - there's no checking for whether or not you read the expected number
  4. Functionality rules and clarity matters; if you can work a little elegance in there, you're stylin'.
  5. On ARM less than Arch V7, you will have your code have an alignment failure- and on V7, you can, IF your runtime is set for it, handle it with a
  6. C and C++ programmers can also use 'gdb'.

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, yea when search on net i read it but i did not use any pointer here is my code : Code: #include int main(){ int input[1001][1001]; int yardimci[1001][1001]; int swap_satir[1001]; Another possible cause is an alignment error.

Starting to sound like I got bad advice. –GeekyOmega Jul 30 '12 at 19:48 Putting in numbers that "work" can be OK, but there should be error handling in Array access (eg. Bus Error C++ PLEASE REMEMBER! Linux Bus Error (core Dumped) You should not leave file in /tmp when you logout.

The time now is 03:52 AM. I wish the C standard would include means of packing/unpacking larger integer types to/from a sequence of smaller integers/characters so as to let the compiler use whatever approach is best on So anyway, each line of the text file contains a word like: 5049 must lean better program now ...

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 I seem grumpy or unhelpful in reply to you, or tell you you need to demonstrate more effort before you can expect help, it is likely you deserve it. The program compiles perfectly.
