stack-overflow

问题 Just started re-learning Haskell (did it at uni but forgot most of it) and thought I would implement a Fibonacci function to start of with. However, I keep getting a stackoverflow, even for very small n . Can anyone spot any problems with my function? fib :: Integer -> Integer fib 0 = 0 fib 1 = 1 fib n = fib (n-1) + fib (n+1) 回答1: You have an error in your fibonacci formula: fib :: Integer -> Integer fib 0 = 0 fib 1 = 1 fib n = fib (n-1) + fib (n-2) Note the very last term where there is n-2

问题 Stack overflow exception is the .NET exception (error) that is thrown when the limited memory available for the execution stack is exhausted. This is almost always caused by an infinite recursion, which ultimately results in too many nested method calls. The following code will throw a stack overflow exception when trying to set a value. public String Name { get{return Name;} set{Name = value;} } I know the references are stored in stack(here its Name) and Objects are stored in Heap(String

问题 I'm getting a 'System.StackOverflowException' in my .NET MVC project after the View has been sent to the Client. The View renders correctly, so the Client side sees no error. However, the server crashes with the StackOverflow Exception afterwards. I've only tested this in IISExpress/VisualStudio, not in IIS. I have html files on a remote server. I'm loading the html files like this: using (WebClient client = new WebClient() {Credentials = new NetworkCredential(Username, Password)}) { string

问题 Want to add an alert box like stackoverflow. i saw some good examples but not something i want. I want different messages that are appearing on different occasions. ex. I want this msg from C# code when user logins. Also when user places an order. or something is wrong. This answer is good but the message is appearing on page load. Another example demonstrate the same. 回答1: You need to create a generic-http-handler or web service or page-method and call it through jQuery and show the message

问题 I have a fortran code compiled with Intel fortran compiler 2013 and VS2010 under windows 7 that started to give me unhandled exceptions without showing the line in which the code was crashing. Usually an error like this was showing up: Unhandled exception at 0x73e1d3d2 in GRIB2METEOriparto.exe: 0xC0000005: Access violation writing location 0x00240ef4.... and the call stack had only dbghelp.dll or verifies.dll and no source available. I moved my source files under Cygwin, I compiled with

问题 To explain my question: I have a simple vector array titled enemies , that holds objects of Enemies . In my level selection menu for the levels i have in-game, when the player clicks on a level i push back all the enemies for that given level into the vector array. Currently i only have 3 levels fully done with all their enemies, today when trying to-do the forth level, now i keep getting a stack overflow. And i'm not sure why this is happening, i mean surely the array is only ever assigned

问题 I've got an ASP.NET usercontrol with a panel that I'm using to hide and show the content, that is, <asp:Panel runat="server" ID=pnlContainer"> <!-- Some fairly uninteresting content --> </asp:Panel> I've got a visible property as an overrider, that is, public override bool Visible { get { return pnlContainer.Visible; } set { pnlContainer.Visible = value; } } When I set it I get a stack overflow exception BUT when I change the keyword to new , that is, public new bool Visible { get { return

问题 After recently installing Windows 7 Professional, I'm getting a strange problem removing a TableItem from a populated Table in SWT. It is specific to Windows 7 and to the SWT.VIRTUAL style constant for the table. Consider the following code: table = new Table(parent, SWT.VIRTUAL | Skin.SCROLL_STYLE | SWT.FULL_SELECTION | SWT.BORDER); TableItem item = new TableItem(table, SWT.NONE); item.setText("Table item"); table.remove(0); This causes a StackOverflowError as follows: Caused by: java.lang

问题 The below codes causing StackOverflowError . purpose of the code is to create a json string from java class. for (ControlTransaction crt : ctrList) { crt= new ControlTransaction();// for test, Still issue final Gson gson = new GsonBuilder().registerTypeAdapter( ControlTransaction.class, new ControlTransactionSerializer()).create(); String jsonControlTransactionString = gson.toJson(crt); strList.add(jsonControlTransactionString); } My class looks like public class ControlTransaction implements

问题 In a ASP.Net web application, when you have a stack intensive operation to run, a stackoverflow exception is thrown on IIS when the stack size crosses the IIS set limit of 256K. A regular winform application however has a limit of 1MB. So the exception would not occur when running the same operation in a Winform application. There is no recursion or any other code specific issues here. There are ways to work around the problem like using EditBin on w3wp.exe, but it’s not supported. Other
