Exception Triggered - Qt-Creator The inferior stopped because it triggered an exception.

Qt系列文章目录

前言

#include "MainWindow.h"

#include <QApplication>
#include <QTime>
#include <QDebug>

int main(int argc, char *argv[])
{
    
    
    QApplication a(argc, argv);
    MainWindow w;
//    w.show();

    QTime startTime = QTime::currentTime();
    int iCount[10000000] = {
    
    1};
    int item = 0;
    for(int i : iCount)
    {
    
    
        item = i;
    }

    QTime endTime = QTime::currentTime();
    qDebug() << startTime.msecsTo(endTime);

    return a.exec();
}

今天QtCreator调试时，写了一极其简单的程序，就是计算时间相减，调试时居然报错了：
Exception Triggered - Qt-Creator
The inferior stopped because it triggered an exception.
Stopped in thread 0 by:Exception an at 0xxxxxxxxxxxxx
code:0xcxxxxxxfd:stack-overflow,flags=0x0(first chance).

根据提示：应该是堆栈溢出了

一、错误原因

既然是堆栈溢出，就应该是指针非法，可我的程序里面没有指针鸭？仔细一看原来是我定义的数组太大了：

int iCount[10000000] = {
    
    1};

所以把数组改小一点就不会报错了，可如果您非要用怎么多数组怎么办了，
1.使用new在堆上分配大小了

2.修改QtCreator堆栈大小
打开pro文件，在最后添加：

二、使用步骤

网上说：修改Qt程序的默认栈大小
修改Qt工程配置文件pro
但是在我机器上依然报错
