Qt4.12.2 Debug下正常,Release下程序崩溃

Super Blaze 2020-08-04 01:09:10

奇怪了，这段代码在Qt环境下用Debug下正常读取文本文档，为什么在Release下运行这个功能也会崩或者直接windeployqt编译出来这个功能都会崩，编译器也没有什么特别的提示，只提示：程序异常结束！百度说是跟Release优化代码有关，我一个小白哪懂这么复杂的处理过程呀！我只有25积分了，希望牛人们帮看看纠正下代码。
这个功能是点击PushButton就读取一个文本文档，读取功能的所以代码就是下面这段：

//获取用户桌面路径

    QString desktopPath = QStandardPaths::writableLocation(QStandardPaths::DesktopLocation);

    QFileDialog *fDialog = new QFileDialog(this);

    fDialog->setAcceptMode(QFileDialog::AcceptOpen);

    fDialog->setWindowTitle("请选择关键词文本文件");

    fDialog->setDirectory(desktopPath);

    fDialog->setNameFilter("文档词库(*.txt)");

    fDialog->setFileMode(QFileDialog::ExistingFile);

    fDialog->setViewMode(QFileDialog::List);

    int openStatus = fDialog->exec();

    if(openStatus == 1){

        //获取到用户选择的词库文件路径

        QString keywordpath = fDialog->selectedFiles()[0];

        QFile file(keywordpath);

        bool fileOpenStatus = file.open(QIODevice::ReadOnly | QIODevice::Text);

        if(fileOpenStatus == true){

            QTextStream text(&file);

            text.setCodec("UTF-8");

            //插入库的行位置

            int RowLocation = 0;

            while(text.atEnd() == false){

                RowLocation ++;

                QString line = text.readLine();

                //导入到关键词库

                if(arg == 1){

                    ui->tableWidget_keyword->setRowCount(RowLocation);

                    QTableWidgetItem *word = new QTableWidgetItem(line);

                    ui->tableWidget_keyword->setItem(RowLocation - 1,0,word);

                    ui->formGroupBox_keyeord->setTitle(QString("关键词库 %1/条").arg(RowLocation));

                }else if(arg == 2){

                    ui->tableWidget_description->setRowCount(RowLocation);

                    QTableWidgetItem *description = new QTableWidgetItem(line);

                    ui->tableWidget_description->setItem(RowLocation - 1,0,description);

                    ui->formGroupBox_description->setTitle(QString("描述词库 %1/条").arg(RowLocation));

                }else if(arg == 3){

                    ui->tableWidget_search->setRowCount(RowLocation);

                    QTableWidgetItem *search = new QTableWidgetItem(line);

                    ui->tableWidget_search->setItem(RowLocation - 1,0,search);

                    ui->gridGroupBox_search->setTitle(QString("内容词库 %1/条").arg(RowLocation));

                }else if(arg == 4){

                    ui->tableWidget_videos->setRowCount(RowLocation);

                    QTableWidgetItem *videoAddress = new QTableWidgetItem(line);

                    ui->tableWidget_videos->setItem(RowLocation - 1, 0, videoAddress);

                    ui->gridGroupBox_video->setTitle(QString("搜索词库 %1/条").arg(RowLocation));

                }

                //防止界面假死

                //QApplication::processEvents();

            }

            file.close();

        }else{

            //打开文本文档失败

        }

    }

    if(arg == 1){

        if(ui->tableWidget_keyword->rowCount() != 0){

            //记录关键词库的数量 and 计算生成需要的文件名数量

            wordCount.wordCount = ui->tableWidget_keyword->rowCount();

            int y = htmlQueryWordCount("关键词");

            //计算按关键字数量计算数量

            int num = wordCount.wordCount / y;

            ui->spinBox_number->setValue(num);

            //按计算数量来生成文件名

            for(int x = 0; x < ui->spinBox_number->value(); x ++){

                ui->tableWidget_files->setRowCount(x+1);

                QString key = getRandomString(9);

            }

        }

    }

    fDialog->close();

    fDialog = nullptr;

    delete fDialog;
