The stack typically lives at the upper end of your address space and as it is used 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 whi
may consist of a limited amount of address space, often determined at the start of the program. The size of the call stack depends on many factors, including the programming language, fix stack overflow error machine architecture, multi-threading, and amount of available memory. When a program attempts to

call stack's bounds, which is essentially a 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 http://stackoverflow.com/questions/214741/what-is-a-stackoverflowerror 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, 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 https://en.wikipedia.org/wiki/Stack_overflow 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 standard.[4] Very deep recursion[edit] A recursive function that terminates in theory but causes a call stack buffer overflow in practice can be fixed by transforming the recursion into a loop and storing the function arguments in a stack. This is always possible, because the class of primitive recursive functions is equivalent to the class of LOOP computable functions. Consider this example in C++-like pseudocode: void function (argument) { if (condition) function (argument.next); } stack.push(argument); while (!s
limits and how they present themselves. I started out by discussing the long-running script dialog and then moved on to other performance issues. I thought I had covered most of the annoying and ill-explained JavaScript limits, but https://www.nczonline.net/blog/2009/05/19/javascript-stack-overflow-error/ this past week I ran across another that is worth discussing: stack overflow errors. http://whatis.techtarget.com/definition/stack-overflow I've written about how too much recursion can lead to performance issues. Most browsers have limits on how much recursion is allowed before the script is automatically canceled. This is a limit that is separate from the one determining if the script is long-running. And the limit is really less about recursive calls so much as it stack overflow is about the size of the JavaScript call stack. Not surprisingly, different browsers have different call stack sizes. Also not surprisingly, the method that they use to determine the call stack varies as well. The various call stack sizes I could measure are (give or take, might be off by 1 or 2): Internet Explorer 7: 1,789 Firefox 3: 3,000 Chrome 1: 21,837 Opera 9.62: 10,000 Safari 3.2: 500 Some have said, stack overflow error but I cannot confirm, that IE and Opera's call stack size are somewhat tied to the amount of RAM on the system. All other browsers have this set by a default. It's also worth noting that WebKit seems to have a much higher limit and that Safari imposes a stricter limit on the JavaScript engine. There are two common scenarios in which this limit could be reached. The first is simple recursion, such as: function recurse(){ recurse(); } recurse(); The second is a more devious and harder-to-identify issue, especially in large code bases, where two functions each call the other, such as: function doSomething(){ doSomethingElse(); } function doSomethingElse(){ doSomething(); } doSomething(); In each case, the browser will end up stopping your code and (hopefully) display a message about the issue: Internet Explorer 7: "Stack overflow at line x" Firefox 3:"Too much recursion" Chrome 1: n/a Opera 9.62: "Abort (control stack overflow)" Safari 3.2:"RangeError: Maximum call stack size exceeded." Chrome is the only browser that doesn't display a message indicating the problem. If you see any of these error messages pop up, it means one of the two patterns are involved and need to be changed. There's usually a line number and file name associated with this error, so it's fairly straightforward to d
IT Management Software management stack overflow Definition stack overflow Facebook Like Tweet Google +1 LinkedIn Email Comment RSS Print A AA AAA Part of the Software management glossary: A stack overflow is an undesirable condition in which a particular computer program tries to use more memory space than the call stack has available. In programming, the call stack is a buffer that stores requests that need to be handled. The size of a call stack depends on various factors. It is usually defined at the start of a program. Its size can depend on the architecture of the computer on which the program runs, the language in which the program is written, and the total amount of available memory in the system. When a stack overflow occurs as a result of a program's excessive demand for memory space, that program (and sometimes the entire computer) may crash. In Windows, a stack overflow error can be caused by certain types of malware. The risk of malware exploits can be minimized by staying current with all OS (operating system) updates and program patches, making sure you have the latest patches for all of your Web browsers, and avoiding Web sites and embedded e-mail links that increase the risk of malware attack.
