bus error

[xyz]

I am getting a "bus Error" in my program.
My simulation should run for 20 min..but i am getting bus error after
10 min of my simulation....
if this is the case please tell the reason for the bus error ...and
how to resolve this ??


thanks to all

You have a bug in your code, might be a bad pointer. Use a debugger, or
printf/cout to find the bug and then analyse and fix it.

use a debugger on the core dump

Are you sure that core dump would reveal the issue? It's not the
segmentation fault, which is typically caused by a bad pointer or some
undefined behavior in the code. Bus Error is typically caused by
hardware, meaning that your code could be invoking a low level
functionality.

You have an error on line 42 of your code.

That depends on the machine. Some with generate a bus error for a
misaligned memory access.

If you are getting a "Bus Error" in your program,
chances ARE GOOD that it is a bad pointer or some
undefined behavior in the code, especially if it
can be reproduced on demand. And of course, this is
not meant to say that hardware problems can never be involved.
Usually the software generated bus error is "detected" by the
hardware, and it "reporting" it, which is obviously different than
the hardware literally failing and causing the error (although
there is a line in sand where it could be argued it really is
a hardware problem even though the software "caused" it, but
let's not go there).

use a debugger on the core dump

Are you sure that core dump would reveal the issue? It's not
the segmentation fault, which is typically caused by a bad
pointer or some undefined behavior in the code. Bus Error is
typically caused by hardware, meaning that your code could be
invoking a low level functionality.

Reference:http://en.wikipedia.org/wiki/Bus_error

Did you read the "reference" you're quoting. One of the most
common cases of a bus error is an unaligned access. (Despite
what the article says, on most machines today, trying to access
inexistant memory results in a segment violation, and not a bus
error.)

Whatever the reason for the core dump, however, the core file is
the same.
