The stack typically lives at the upper end of your address space and as it is used stack overflow error c++ up it heads towards the bottom of the address space (i.e. towards zero). Your process also has a heap, which lives at the bottom end of your process. As you allocate memory this heap can grow towards the upper end of your address space. As you can see, there is the potential for the heap to "collide" with the stack (a bit like tectonic plates!!!). The common cause for a stack overflow is a bad recursive call. Typically this is caused when your recursive functions doesn't have the correct termination condition, so it ends up calling itself forever. However, with GUI programming it's possible to generate indirect recursion. For example, your app may be handling paint messages and whilst processing them it may call a function that causes the system to send another paint message. Here you've not explicitly called yourself, but the OS/VM has done it for you. To deal with them you'll need to examine your code. If you've got functions that call themselves then check that you've got a terminating condition. If you have then check than when calling the function you have at least modified one of the arguments, otherwise there'll be no visible change for the recursively called function and the terminating condition is useless. If you've got no obvious recursive functions then check to see if you're calling any l

may consist of a limited amount of address space, often determined at the start of the program. The https://en.wikipedia.org/wiki/Stack_overflow size of the call stack depends on many factors, including the programming language, machine architecture, multi-threading, and amount of available memory. When a program attempts to use http://www.computerhope.com/jargon/s/stacover.htm more space than is available on the call stack (that is, when it attempts to access memory beyond the call stack's bounds, which is essentially a stack overflow buffer overflow), the stack is said to overflow, typically resulting in a program crash.[1] Contents 1 Infinite recursion 2 Very deep recursion 3 Very large stack variables 4 See also 5 References 6 External links Infinite recursion[edit] Main article: Infinite recursion The most common cause of stack overflow is excessively deep or infinite recursion, stack overflow error in which a function calls itself so many times that the space needed to store the variables and information associated with each call is more than can fit on the stack.[2] An example of infinite recursion in C. int foo() { return foo(); } The function foo, when it is invoked, continues to invoke itself, allocating additional space on the stack each time, until the stack overflows resulting in a segmentation fault.[2] However, some compilers implement tail-call optimization, allowing infinite recursion of a specific sort—tail recursion—to occur without stack overflow. This works because tail-recursion calls do not take up additional stack space.[3] C compiler options will effectively enable tail-call optimization; compiling the above simple program using gcc with -O1 will result in a segmentation fault, but not when using -O2 or -O3, since these optimization levels imply the -foptimize-sibling-calls compiler option. Other languages, such as Scheme, require all implementations to include tail-recursion as part of the language sta
usage occurs on the call stack, which is where information is stored relating to the active subroutines in the program. The call stack has a limited amount of memory available to it. Its size is determined by the programming language, the architecture, whether multi-threading is available on the CPU, and how much memory is available. Typically, when a stack overflow error occurs, the program crashes and can either freeze or close the program. Any unsaved data or work is lost. The stack overflow error is often caused by either an infinite loop in the programming, or the creation of variables that are too large for the size of the call stack. The stack overflow problem is not as prevalent on the newer operating systems, however, because of the small footprint on mobile devices it can become challenging. If your operating system on your mobile device is giving you a stack overflow error you may have too many apps running, a virus is using stack space, or your device has bad hardware. Check your app usage and virus protection and run a memory diagnostic app on your mobile device to see if this helps clear up your error. Related pages Stack overflow system halted error.
