fault

I have this following very simple code, that works perfectly: void func(int *tab) { return; } int main() { int maxsize = 999*999; int tabs[maxsize][6]; return 0; } However, when I modify the main such that I obtain this, it crashes. int main() { int maxsize = 999*999; int tabs[maxsize][6]; func(tabs[0]); return 0; } Do you have any idea why? I would really appreciate your help on this, thank you ^^ So although the standard does not talk about stacks most modern implementations will put automatic variables on the stack and the stack will typically between 1M and 8M which you will overflow with

昨天把Qtopia 2.2.0编译移植好了后，今天打算写一个hello world测试一下。拿到可执行文件后，下到板子上，加上-qws选项运行，结果直接Segmentation Fault。代码如下： #include "qapplication.h" #include "qpushbutton.h" #include <stdio.h> #include <unistd.h> int main(int argc, char *argv[]) { QApplication app(argc,argv); QPushButton *hello = new QPushButton("Hello World.",0); //printf("hello.\n"); hello->resize(640,480); //hello->move(100,100); //printf("hello.move.\n"); hello->show(); app.setMainWidget(hello); //printf("hello.show.\n"); while(0) { printf("show...\n"); sleep(1); } return app.exec(); } 检查代码，没问题，每一句后面加上printf语句，发现前面都没有问题，但只要执行到 return app.exec()

I'm interested in properly handling Faults within a WCF REST Service client. While using any of WebClient, WebRequest, or HttpWebRequest like so: try { HttpWebRequest req = (HttpWebRequest)HttpWebRequest.Create(uri); req.Method = "GET"; HttpWebResponse resp = (HttpWebResponse)req.GetResponse(); // ...process... } catch (WebException wex) { string exMessage = wex.Message; if (wex.Response != null) { using (StreamReader r = new StreamReader(wex.Response.GetResponseStream())) exMessage = r.ReadToEnd(); // the fault xml is available here, really need to parse? and how? } } I can see in Fiddler

My program compiles fines but upon inputting a file I get a "Segmentation fault (core dumped)" error. Am I not handling the ostream correctly? #include <std_lib_facilities.h> struct Reading { int hour; double temperature; Reading(int h, double t): hour(h), temperature(t) { } bool operator<(const Reading &r) const; }; bool Reading::operator<(const Reading &r) const { // stub version if (temperature < r.temperature){ return true; } else if (r.temperature < temperature) { return false; } } /* * function declarations */ ostream& operator<<(ostream& ost, const Reading &r); vector<Reading> get_temps

So I've been developing this program for a while now... Its meant to act as an asset manager (and potentially more in the future) for our IT team. I have 2 services which we'll refer to as "Manager" and "IAM" for right now. The "Manager" does all things managerial for all services (currently only the inventory asset manager known as "IAM") such as automatic updates, etc., while the asset manager does its job. Anyways, its been working great for a while now. Recently I implemented an automatic updating feature (actually still needing to be tested and likely debugged). While doing this, I needed
