Stack overflow exception in c# setter

问题 This is simple to explain: this works using System; using ConstraintSet = System.Collections.Generic.Dictionary<System.String, double>; namespace ConsoleApplication2 { class test { public ConstraintSet a { get; set; } public test() { a = new ConstraintSet(); } static void Main(string[] args) { test abc = new test(); Console.WriteLine("done"); } } } this does not using System; using ConstraintSet = System.Collections.Generic.Dictionary<System.String, double>; namespace ConsoleApplication2 {

How can I increase the maximum call stack size in Node.js

别等时光非礼了梦想. 提交于 2019-11-27 07:24:34
This is different to other questions regarding an error message in Node that reads RangeError: Maximum call stack size exceeded in that I know exactly why I'm getting this error message. It's happening because I'm recursing, recursing quite a lot in fact. Thanks. From node --help : node --max-stack-size=val Update: as the comments indicate, even though the help text still lists the --max-stack-size option, in node v0.10.x you need to use --stack-size instead. node --stack-size=val In node version 5 and 6, I have verified that the option to set maximum stack size is "--stack_size" (with an

Why does the stack address grow towards decreasing memory addresses?

好久不见. 提交于 2019-11-27 06:49:13
I read in text books that the stack grows by decreasing memory address; that is, from higher address to lower address. It may be a bad question, but I didn't get the concept right. Can you explain? First, it's platform dependent. In some architectures, stack is allocated from the bottom of the address space and grows upwards. Assuming an architecture like x86 that stack grown downwards from the top of address space, the idea is pretty simple: =============== Highest Address (e.g. 0xFFFF) | | | STACK | | | |-------------| <- Stack Pointer (e.g. 0xEEEE) | | . ... . | | |-------------| <- Heap

How do I print functions as they are called

In debugging a Python script, I'd really like to know the entire call stack for my entire program. An ideal situation would be if there were a command-line flag for python that would cause Python to print all function names as they are called (I checked man Python2.7 , but didn't find anything of this sort). Because of the number of functions in this script, I'd prefer not to add a print statement to the beginning of each function and/or class, if possible. An intermediate solution would be to use PyDev's debugger, place a couple breakpoints and check the call stack for given points in my

How exactly does the callstack work?

问题 I'm trying to get a deeper understanding of how the low level operations of programming languages work and especially how they interact with the OS/CPU. I've probably read every answer in every stack/heap related thread here on Stack Overflow, and they are all brilliant. But there is still one thing that I didn't fully understand yet. Consider this function in pseudo code which tends to be valid Rust code ;-) fn foo() { let a = 1; let b = 2; let c = 3; let d = 4; // line X doSomething(a, b);

The call stack does not say “where you came from”, but “where you are going next”?

早过忘川 提交于 2019-11-27 03:51:58
In a previous question ( Get object call hierarchy ), I got this interesting answer : The call stack is not there to tell you where you came from. It is to tell you where you are going next. As far as I know, when arriving at a function call, a program generally does the following: In calling code: store return address (on the call stack) save registers' states (on the call stack) write parameters that will be passed to function (on the call stack or in registers) jump to target function In called target code: Retrieve stored variables (if needed) Return process : Undo what we did when we

Is stack memory contiguous?

时光毁灭记忆、已成空白 提交于 2019-11-27 03:48:49
问题 How does the compiler enforce the stack memory to be contiguous, does it cause the memory to be moved everytime while the program is running or does it reserve the memory on stack needed by program before running it? 回答1: The stack for a given thread is often contiguous in virtual memory (on Linux and similar systems, and in user mode in Windows). The Windows kernel (in Windows Vista and above) and z/OS allow discontiguous stacks in virtual memory, and GCC 4.6 will also allow that. The

Can a C compiler rearrange stack variables?

我怕爱的太早我们不能终老 提交于 2019-11-27 02:18:05
问题 I have worked on projects for embedded systems in the past where we have rearranged the order of declaration of stack variables to decrease the size of the resulting executable. For instance, if we had: void func() { char c; int i; short s; ... } We would reorder this to be: void func() { int i; short s; char c; ... } Because of alignment issues the first one resulted in 12 bytes of stack space being used and the second one resulted in only 8 bytes. Is this standard behavior for C compilers
