Bus Error 10 (core Dumped)


The Intel x86 is, by the way, not such an architecture, it would allow the access (albeit execute it more slowly). You probably do not have access to such a system. That's what is causing the bus error in this case. share|improve this answer edited Jan 15 '10 at 7:28 answered Jan 15 '10 at 4:21 Seth 26k55497 3 On modern hardware that results in a segmentation fault, not a bus http://patricktalkstech.com/bus-error/bus-error-core-dumped-c.html

An attempt to access memory that isn't physically present would also give a bus error, but you won't see this if you're using a processor with an MMU and an OS Success! Unaligned access[edit] Most CPUs are byte-addressable, where each unique memory address refers to an 8-bit byte. Texan via Arizona, out of his element!

Functionality rules and clarity matters; if you can work a little elegance in there, you're stylin'. Some systems may have a hybrid of these depending on the architecture being used.

How To Debug Bus Error

You've used an address that's meaningless to the system, or the wrong kind of address for that operation. 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. 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; Source and you're going to get nasty things happening to you.
