What Is Stack Underflow

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 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
may consist of a limited amount of address space, often determined at the start of the program. The size how to avoid stack overflow in c 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 more stack overflow in c examples 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 buffer overflow), http://stackoverflow.com/questions/214741/what-is-a-stackoverflowerror 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, in which https://en.wikipedia.org/wiki/Stack_overflow 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 standard.[4] Very deep recursion[edit] A
the other has to do with the amount of memory used to store data. Each program has a section of memory allocated for a stack. The stack is used to store internal data for http://www.computerhope.com/jargon/o/overflow.htm the program and is very fast and keep track of return addressing. In other https://support.microsoft.com/en-us/kb/895194 words, a program may jump to an area that reads some data from the hard drive, then it returns from that routine to continue processing the data. The stack keeps track of the originating address, and the program uses that for the return. Kind of like leaving breadcrumbs to find your way back. That being said, the stack has stack overflow a limited amount of storage space. Between using it for storing return addresses, and as well as memory usage for storing variables, it can run out and all of the little bits of data overflow and cause programs to crash. 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 stack overflow in is giving you a stack overflow error you may have too many apps running. You may have a virus using stack space. You could even have hardware damage that could cause a stack overflow error message. 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. An overflow error that is created by storage assignment is referenced as a data type overflow. What this means is that a certain data type used for storing a piece of data was not large enough to hold the data. As an example, if you have a box that is supposed to hold ten cans of soup, but you have twelve cans to put in it then you have an overflow of two cans of soup. By the same token certain data types can only store numbers of a certain size. If a data type is a single byte, and the data to be stored is greater than 256 then there is an overflow error generated and the program crashes because it has corrupted data. This type of error typically only happens with older machines trying to run modern operating systems since the capacity of the operating system over shadows the capacity of the hardware. In other wo
