(July 2015) (Learn how and when to remove this template message) In computing, a bus error is a fault raised by hardware, notifying an operating system (OS) bus error c++ that a process is trying to access memory that the CPU cannot bus error in linux physically address: an invalid address for the address bus, hence the name.

these are much rarer than segmentation faults, which occur primarily due to memory access violations: problems in the logical address or permissions. On POSIX-compliant platforms, bus errors usually result in the
How To Debug Bus Error
SIGBUS signal being sent to the process that caused the error. SIGBUS can also be caused by any general device fault that the computer detects, though a bus error rarely means that the computer hardware is physically broken—it is normally caused by a bug in a program's source code.[citation needed] Bus errors may also be raised for certain other paging errors; see how to solve bus error in linux below. Contents 1 Causes 1.1 Non-existent address 1.2 Unaligned access 1.3 Paging errors 2 Example 3 References Causes[edit] There are at least three main causes of bus errors: Non-existent address[edit] Software instructs the CPU to read or write a specific physical memory address. 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 address. If no other hardware responds, the CPU raises an exception, stating that the requested physical address is unrecognized by the whole computer system. Note that this only covers physical memory addresses. 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 the difference. Unaligned access[edit] Most CPUs are byte-addressable, where each unique memory address refers to an 8-bit byte. 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 th

What would cause a bus error? I searched google for a cause, but came up with some conflicting reports... Could it be caused by [lack of] disk space? A lot of the pages I found mentioned linking with the incorrect versions of the library. But in that case, would it compile correctly? Basically, I am curious as to why we had a job dump core on a bus error. It ran http://www.unix.com/unix-for-dummies-questions-and-answers/3109-bus-error.html nearly to normal completion time, then simply poo-pood. In the case that it may make a difference, it's a job that interfaces with an Oracle database on HP-UX 11. The things that had changed were that the process was recompiled, AND we were at 96% (df -k) on that disk... Not too important for me to know right now, but I am curious, and who wants to wait for developers to tell me what happened?

This is almost always the result of dereferencing a pointer that contains an illegal value. 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...

OmniFocus with the scripting bridge. It's working, but I'm have problems with creating new projects: #!ruby require 'osx/cocoa' include OSX OSX.require_framework 'ScriptingBridge' omnifocus = SBApplication.applicationWithBundleIdentifier_("com.omnigroup.OmniFocus") p = { "name" => "Foo" } Project = omnifocus.classForScriptingClass_("project") proj = Project.alloc(); proj.initWithProperties_(p); # this causes a bus error # proj.get(); # this also causes a bus error omnifocus.documents()[0].projects().insertObject_atIndex_(proj,0) I get this error travis-2:~ mark$ ruby testscript ruby: unknown type name "item". /System/Library/Frameworks/RubyCocoa.framework/Resources/ruby/osx/objc/oc_wrapper.rb:50: [BUG] Bus Error ruby 1.8.6 (2007-09-24) [universal-darwin9.0] Abort trap What am I doing wrong? RobTrew2008-01-22, 09:40 AMHaven't used Scripting Bridge, but the problem may be that you need to use a constructor which is a method of the document class. The applescript analogy would be something like: tell application "OmniFocus" tell front document set oProj to make new project end tell end tell Carl Bourne2008-02-16, 05:37 PMHi I'm trying to do a similar thing with OmniPlan. Did you ever get this to work? Are there any examples on using Ruby with new Leopard scripting bridge? Thanks, Carl RobTrew2008-02-16, 11:08 PMFWIW, ensuring that you use constructors which are methods of the appropriate parent class would look something like this in applescript for Omniplan. The pattern would be analogous in Ruby. tell application "OmniPlan" set oProj to project of document of window 1 tell oProj set oTopLevelTask to make new task end tell tell oTopLevelTask set oSubTask to make new task end tell end tell jedediah2008-02-21, 10:38 PMCan't say I've used the scripting bridge, but I do have a handful of scripts working using the rbosa gem. It maps most applescript stuff to ruby very idiomatically, and I've been very impressed. Quick example from just a few minutes ago: #!/usr/bin/ruby require 'rubygems' require 'rbosa' of = OSA.app 'OmniFocus' shopping_list = of.default_document.contexts['Shopping'] ... I did have to write some functions to make the square bracket notation functional, but overall, it was very easy. If you do forge ahead with the scripting bridge, I'd love to know what you think of it. 2shortplanks2008-02-28, 12:37 AMI've actually given up on this whole Scripting Bridge thing. It requires the authors of the application to write their "scripting" in a particular way, something that O
