C Error Segmentation Fault
a segmentation fault? Is it different in C and C++? How are segmentation faults and dangling pointers related? c++ c segmentation-fault share|improve this question edited Jun 1 at 2:40 Jonathan Leffler 438k61508822 asked Feb 27 '10 at 9:23 mag 5,96394053 9 If that's the case, why in my case the compiler complained nothing, it all went smooth, but at run time the system throws a segmentation fault (core dump)? segmentation fault in c T_T –Jim Raynor Jan 5 '15 at 19:46 1 Just a memory dump when something goes wrong! –resultsway Apr 25 '15 at 1:18 2 @pinouchon: Funny, but when does a compiler have a thing to do with seg faults? Isn't it more the run time enviroment? –Zaibis Jul 30 '15 at 13:23 add a comment| 10 Answers 10 active oldest votes up vote 349 down vote accepted Segmentation fault is a specific kind of error caused by accessing memory that “does not belong to you.” It’s a helper mechanism that keeps you from corrupting the memory and introducing hard-to-debug memory bugs. Whenever you get a segfault you know you are doing something wrong with memory – accessing variable that has already been freed, writing to a read-only portion of the memory, etc. Segmentation fault is essentially the same in most languages that let you mess with the memory management, there is no principial difference between segfaults in C and C++. There are many ways to get a segfault, at least in the lower-level languages such as C(++). A common way to get a segfault is to dereference a null pointer: int *p = NULL; *p = 1; Another segfault happens when you try to write to a portion

segmentation fault (often shortened to segfault) or access violation is a
Segmentation Fault (core Dumped) C
fault raised by hardware with memory protection, notifying an operating system (OS) about a memory access violation; on how to debug segmentation fault x86 computers this is a form of general protection fault. The OS kernel will, in response, usually perform some corrective action, generally passing the fault on to the http://stackoverflow.com/questions/2346806/what-is-a-segmentation-fault offending process by sending the process a signal. Processes can in some cases install a custom signal handler, allowing them to recover on their own,[1] but otherwise the OS default signal handler is used, generally causing abnormal termination of the process (a program crash), and sometimes a core dump. Segmentation faults are a common class of error in https://en.wikipedia.org/wiki/Segmentation_fault programs written in languages like C that provide low-level memory access. They arise primarily due to errors in use of pointers for virtual memory addressing, particularly illegal access. Another type of memory access error is a bus error, which also has various causes, but is today much rarer; these occur primarily due to incorrect physical memory addressing, or due to misaligned memory access – these are memory references that the hardware cannot address, rather than references that a process is not allowed to address. Newer programming languages may employ mechanisms designed to avoid segmentation faults and improve memory safety. For example, the Rust programming language employs an 'Ownership'[2] based model to ensure memory safety.[3] Contents 1 Overview 2 Causes 3 Handling 4 Examples 4.1 Writing to read-only memory 4.2 Null pointer dereference 4.3 Buffer overflow 4.4 Stack overflow 5 See also 6 References 7 External links Overview[edit] Example of human generated signal A null pointer dereference on Windows 8 A segmentation fault occurs when a program attempts to access a memory

Fresh clone from repository of 3.x version or the 2.x version 2. GCC 4.8+ (http://nuwen.net/mingw.html version 10.4 x86 used on Windows OS) 2. CMake 2.8+ using either Code::Blocks MinGW make or MinGW make files (NO Demos, error segmentation fault CPU Demos, Extras, Multithreading, Unit Tests, Custom Vector Math, Double Precission or GLUT, just the core libraries) 3. Build type: Release (anything that has -O2 or -O3) 4. That's it. Start building. cc1plus.exe will segfault on btInternalEdgeUtility.cpp:310:2 NOTE: The library compiles fine without any optimizations. What is the expected output? What do you see instead? cc1plus sould exit without segfaulting. cc1plus exits segfaulting. What version of the product are you using? On what operating system? Fresh 2.x repository clone at revision r2722 (same problem with official releases or previous revisions) same for 3.x Windows 7 or XP Please provide any additional information below.
