Linq to SQL throwing a StackOverflowException

由 懵懂的女人 提交于 2019-12-07 00:58:53
问题 I'm executing a pretty simple query using Linq to SQL. I'm creating the expression and then passing it to the Where() extension method. The Linq internals are throwing a StackOverflowException when I attempt to actually execute the query. Here is the code: int expectedCount = 4; Expression<Func<Thing, bool>> expression = ...; //Expression looks like (LocaleID = 1 && GenderID ==1 && (TimeFrameID == 2007 || TimeFrameID == 2008)) using (XYZDataContext context = new XYZDataContext()) { int count

determine stack depth in javascript using javascript

由 扶醉桌前 提交于 2019-12-07 00:55:40
问题 Is there a way to determine the stack depth of all functions being executed in javascript by using javascript itself? I'm thinking it might involve modifying the Function prototype, but I really don't have any idea. Additionally, it would be nice to be able to break anytime the stack depth were sufficiently high. The reason for this is that I have a stack overflow error in IE which is apparently not debuggable. I'm lazy and I would rather not have to hunt through the code that I'm maintaining

Stack overflow at line 0

由 ぃ、小莉子 提交于 2019-12-06 23:58:58
问题 I have a form validation script that is unfortunately returning the Stack overflow at line 0 alert box shortly before crashing (IE7) and just straight up crashes in IE8 (It does work first, very slowly). I have made a jsFiddle for your testing pleasure: http://jsfiddle.net/yuNXm/2/ the stack overflow occurs after you have entered a value into an input which requires validation and then lose it's focus. (the email field is ajax driven so won't function there). The relevant Javascript: jQuery

Why doesn't this recursion produce a StackOverFlowException?

问题 What is wrong with this code: using System; namespace app1 { static class Program { static int x = 0; static void Main() { fn1(); } static void fn1() { Console.WriteLine(x++); fn1(); } } } I compile this piece of code using this command: csc /warn:0 /out:app4noex.exe app4.cs When I double click on the exe, it doesn't seem to throw the exception (StackOverFlowException), and keep running forever. Using visual studio command prompt 2010, but I also have vs 2012 installed on the system, all up

Why am I not getting a stack overflow?

问题 EDIT Before you got excited see important edits in the end and if you're still curious these are reported as: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=696222 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=696263 I have been trying a piece of code and surprised to see that I didn't get a stackoverflow. Trying to simplify things I even got this far: #include <stdio.h> int main() { int i; /* 1,500,000,000 x 4 bytes = 6,000,000,000 bytes = 6GB */ int size = 1500000000; int arr[size];

VERY strange stack overflow in C++ program

由 廉价感情. 提交于 2019-12-06 09:37:10
I wrote a program some time ago (Mac OS X, C++, SDL, FMOD) and it perfomed rather good. But lately I wanted to extend its functionality and added some more code to it. And now, when I run it and try to test the new functionality, the program crashes with SIGABRT. Looking into debugger, on function stack I see: _kill kill$UNIX2003 raise __abort __stack_chk_fail odtworz <-- my function that was was modified As far as I know, "__stack_chk_fail" indicates a stack overflow. But that's not the weirdest thing about it. In this function "odtworz", I have some code like this: ... koniec = 0; while (

Tail recursion issue

由 依然范特西╮ 提交于 2019-12-06 06:43:51
问题 We were experimenting with parallel collections in Scala and wanted to check whether the result was ordered. For that, I wrote a small function on the REPL to do that check on the very large List we were producing: def isOrdered(l:List[Int]):Boolean = { l match { case Nil => true case x::Nil => true case x::y::Nil => x>y case x::y::tail => x>y & isOrdered(tail) } } It fails with a stackOverflow (how appropriate for a question here!). I was expecting it to be tail-optimized. What's wrong? 回答1:
