This was such a stupid mistake and I fixed it. based on MAC address -- why not "based on MAC addresses"? Not only does it get the value wrong, but it gets x and y wrong as well. Pointers are a little like scalars -- they too can be declared as globals, locals or parameters, and can be assigned values, passed as parameters, and returned from procedures.

What would have been the behavior on a non-buggy OS? –Calvin Huang Feb 17 '14 at 0:55 add a comment| up vote 3 down vote One classic instance of a bus I was allowed to enter the airport terminal by showing a boarding pass for a future flight. Not the answer you're looking for? It's not so much type conversion as you're doing type conversion on a pointer that you've done pointer math on.

  1. Why is nuclear waste more dangerous than the original nuclear fuel?
  2. s2 = 0x%lx, i = 0x%lx\n", (long unsigned int) s, (long unsigned int) s2, i); printf("s[0] = %c, s[1] = %c, *s2 = %c\n", s[0], s[1], *s2); } UNIX> make p9
  3. EDIT : The moment you malloc() and copy you are playing with a copy of the original string and ptr is not of 'const char *' type, instead it is 'char

  5. The second doesn't, as you make a copy of data and then modify it.
  6. As a matter of speed this is in +/-3% speed of the classical DATUM* + polynomial access method.

Randomly pick a word, jumble it and try to guess it. In fact, s2 becomes an illegal address, which results in a segmentation fault: On our sparcs: UNIX> p8 i = -268441312 (0xefffe920) s = -268441312 (0xefffe920) s = 0xefffe920. You can pass them as parameters to procedures, and return them from procedures without worrying about anything going awry. Bus Error 10 Mac In other words, the array goes from 0x0 to 0x7fffffff.

I probably will tinker around with a way to get this work using fread directly. Linux Bus Error Core Dumped Or is it inevitable once a certain point in development is reached? A better way to read a file is with fread() (see http://www.cplusplus.com/reference/clibrary/cstdio/fread/). However, in general you should always be sure that your code will work when pointers and ints are different sizes.

And shm_open says that it generates objects of size 0: The shared memory object has a size of zero. Bus Error Vs Segmentation Fault These days, memory is so big that we don't generate core dumps, although we could if we had to.) The reason element 0 is inaccessible is that it's a common bug Meaning of '2> >(command)' Redirection in Bash Java Scanner Class bad character "®" Class armor proficiency vs. Create new tab config in admin magento2 error sorting?

For example, if i is an (int *), then if i is not a multiple of 4, dereferencing i will be an error. Last modification: Tue Jan 13 13:12:09 EST 2015 TYPES in C In C, there are three kinds of types that variables can have -- scalars, aggregates, and pointers. I tried introducing a local variable in the strcattest function that would behave as a copy of string1 but that got the compiler yelling at me for returning a local variable Note: The gray areas my not be system memory, but it is not memory that has been declared.

Thus, in the following struct: struct { char b; int i; } The whole struct will be 8 bytes -- 1 for b, 3 unused, and 4 for i. This array has 232 or 264 elements.

Sigbus Let's take a look at the following code in C++, which declares two intdouble's, sets one's variables, and then copies one to the other (id3.cpp): #include #include using namespace naming the variable to be the same as the function is poor - it's called shadowing, and can lead to some rather weird scope problems (just try making your function recursive

In various fields of research (perhaps wider), the slang "bus error" has a different meaning, which I think could be a relevant answer. To do that, you multiply sizeof(type) by the number of elements. share|improve this answer answered May 5 '11 at 3:43 Claudiu 95.9k92311496 By the way, you should not cast the return value from malloc. –David Heffernan May 5 '11 at

Oh, and sorry about the messy code. #include #include #include #include #include int x = 0; int a[]; void swap (int v[], int i, int j) { How to have table blanks as zeros? And so on. This book is dated, but it remains very useful, and no C text that I've seen is more succinct.

It wouldn't be stack overflow protection, just memory write protection (this is a security hole if your program can rewrite itself). –Mark Lakata Jun 21 at 17:11 add a comment| up A bus error is trying to access memory that can't possibly be there.
