Qt：分配堆对象在ucrtbase.dll

Question

我正在关注本文，以创建一个示例Qt属性浏览器项目：https://doc.qt.io/archives/qq/qq18-propertybrowser.html

构建应用程序时，分配QtTreePropertyBrowser对象时它会崩溃

#include <QApplication>
#include <qtpropertybrowser.h>
#include <QtIntPropertyManager>
#include <qttreepropertybrowser.h>
#include <QtEnumPropertyManager>
#include <QtEnumEditorFactory>
#include <QtGroupPropertyManager>
#include <QtSpinBoxFactory>

int main(int argc, char *argv[])
{
    QApplication app(argc, argv);

    /* create props
     **/
    auto pIntManager = new QtIntPropertyManager;
    auto pPropPriority = pIntManager->addProperty("Priority");

    pPropPriority->setToolTip("Task priority");
    pIntManager->setRange(pPropPriority, 1, 5);
    pIntManager->setValue(pPropPriority, 3);

    auto pEnumManager = new QtEnumPropertyManager;
    auto pReportType = pEnumManager->addProperty("Report type");
    pReportType->setToolTip("Some report");

    const auto types = QStringList{} << "bug" << "suggestion" << "todo";
    pEnumManager->setEnumNames(pReportType, types);
    pEnumManager->setValue(pReportType, 1); // "suggestion"

    /* factory
     **/
    auto pSpinFactory = new QtSpinBoxFactory;
    auto pEnumFactory = new QtEnumEditorFactory;

    /* group
     **/
    auto pGroupManager = new QtGroupPropertyManager;
    auto pTask1 = pGroupManager->addProperty("Task 1");
    pTask1->addSubProperty(pPropPriority);
    pTask1->addSubProperty(pReportType);

    /* add props to browser
     **/
    auto pTreeBrowser = new QtTreePropertyBrowser; // <-- crashes here
    pTreeBrowser->setFactoryForManager(pIntManager, pSpinFactory);
    pTreeBrowser->setFactoryForManager(pEnumManager, pEnumFactory);
    pTreeBrowser->addProperty(pTask1);
    pTreeBrowser->show();

    return app.exec();
}
