自一周以来，我的 Qt 应用程序无法正常工作。我不熟悉这种堆损坏、访问冲突等东西。现在我知道它“很痛”，-)

同时我安装了应用程序验证器。我正在使用 VS2010、Qt 4.8.4、qwt 6.0.0。现在我将 GUI 类减少到最低限度，但仍然通过应用程序验证程序获得访问冲突。这是图形用户界面代码：

#include "mygui.h"
#include <QtGui/QApplication>

int main(int argc, char *argv[])
{
    QApplication a(argc, argv);
    MYGUI w;
    w.show();
    return a.exec();
}

mygui.h：

#ifndef PFEGUI_H
#define PFEGUI_H

#include <QtGui/QMainWindow>
#include "ui_mygui.h"

#include <myengine.hpp>

class MYGUI : public QMainWindow
{
    Q_OBJECT

public:
    MYGUI(QWidget *parent = 0, Qt::WFlags flags = 0);
    ~MYGUI();

    Ui::MYGUIClass ui;

private:
    boost::shared_ptr<MYengine> myEngine_; 
    boost::shared_ptr<QMenu> treeWidgetMenu_;
    boost::shared_ptr<QAction> treeWidgetMenuDeleteAction_;

};

mygui.cpp:

#include "mygui.h"

MYGUI::MYGUI(QWidget *parent, Qt::WFlags flags)
    : QMainWindow(parent, flags)
{
    ui.setupUi(this);
    myEngine_ = boost::shared_ptr<MYengine>(new MYengine());
}

MYGUI::~MYGUI() {}

和大型自动生成的 ui_mygui.h （由于字符限制，我在中间跳过了一些部分）：

这编译没有任何问题。但是当我启动应用程序（使用应用程序验证程序）时，我在方法之后得到一个触发断点

void setupUi(QMainWindow *MYGUIClass)

在ui_mygui.h中完成，进入MYengine的构造函数。没有执行构造函数的任何行，它只是触发一个断点。这是验证者报告：

======================================== VERIFIER STOP 00000013：pid 0x1CDC：第一次机会访问违规对于当前堆栈跟踪。

0AF79000 : Invalid address causing the exception.
00E15057 : Code address executing the invalid access.
0032F134 : Exception record.
0032F184 : Context record.

======================================== 这个验证器停止是可继续的。调试后使用“go”继续。

========================================

如果我只是删除单行

myEngine_ = boost::shared_ptr<MYengine>(new MYengine());

在 mygui.cpp 中，Gui 打开，没有应用程序验证程序断点，一切似乎都运行良好。

我完全迷路了。class MYengine 是一个嵌入在静态库中的大型类，还有数百个附加类。错误发生在 Myengine 的构造函数的第一行执行之前。那么为什么有或没有上述行的行为如此不同？任何想法将不胜感激。这段代码开始让我成功，-(

在不知道其余代码的情况下，我很确定您不应该将 Qt 指针放入 boost 共享指针中 - Qt 有自己的对象生命周期管理，并且会在不询问共享指针的情况下删除内存，因此您最终可能会得到 boost - 指向已释放内存的指针。但这仅适用于

boost::shared_ptr<QMenu> treeWidgetMenu_;
boost::shared_ptr<QAction> treeWidgetMenuDeleteAction_;

应该分别是 QMenu* 和 QAction*。

我假设 MYengine 不是 Qt 类。或许，您应该向我们展示 MyEngine 的接口，以便我们了解，为什么指向 MyEngine 的共享指针会造成麻烦。
