编译出来的库文件将QDateTimeEdit 或者 QTimeEdit类加入布局时会阻塞QT图形界面的线程

硬件：s3c2440 QT版本： qt-embedded-linux-opensource-src-4.4.3当配置使用release时：./configure -prefix /home/ssss/qt-embedded-linux-opensource-src-4.4.3 -release -shared -fast -pch -no-qt3support -qt-sql-sqlite -no-libtiff -no-libmng -qt-libjpeg -qt-zlib -qt-libpng -qt-freetype -no-openssl -nomake examples -nomake demos -nomake tools -optimized-qmake -no-largefile -no-webkit -no-phonon -no-nis -no-opengl -no-cups -no-xcursor -no-xfixes -no-xrandr -no-xrender -no-xkb -no-sm -no-xinerama -no-xshape -no-separate-debug-info -xplatform qws/linux-arm-g++ -embedded arm -depths 16 -no-qvfb -qt-gfx-linuxfb -no-gfx-qvfb -no-kbd-qvfb -no-mouse-qvfb -qt-kbd-usb -confirm-license -qt-mouse-tslib -I/home/share/qt-box/tslib/include -L/home/share/qt-box/tslib/lib编译出来的库文件将QDateTimeEdit 或者 QTimeEdit类加入布局时会阻塞QT图形界面的线程而相同的代码使用debug编译的库文件则能在布局中显示：./configure -prefix /home/ssss/qt-embedded-linux-opensource-src-4.4.3 -debug -shared -fast -pch -no-qt3support -qt-sql-sqlite -no-libtiff -no-libmng -qt-libjpeg -qt-zlib -qt-libpng -qt-freetype -no-openssl -nomake examples -nomake demos -nomake tools -optimized-qmake -no-largefile -no-webkit -no-phonon -no-nis -no-opengl -no-cups -no-xcursor -no-xfixes -no-xrandr -no-xrender -no-xkb -no-sm -no-xinerama -no-xshape -no-separate-debug-info -xplatform qws/linux-arm-g++ -embedded arm -depths 16 -no-qvfb -qt-gfx-linuxfb -no-gfx-qvfb -no-kbd-qvfb -no-mouse-qvfb -qt-kbd-usb -confirm-license -qt-mouse-tslib -I/home/share/qt-box/tslib/include -L/home/share/qt-box/tslib/lib使用的代码：DateEdit = new QDateTimeEdit();DateEdit->setDateTime(QDateTime::currentDateTime());DateEdit->setDisplayFormat("dd/M/yyyy");DateEdit->setCalendarPopup(true);dateLabel = new QLabel(tr("&Date:"));//dateLabel->setBuddy(dateEdit);timeEdit = new QTimeEdit(QTime::currentTime());timeEdit->setAlignment(Qt::AlignCenter);timeLabel = new QLabel(tr("&Time:"));timeLabel->setBuddy(timeEdit);OKbuttonBox = new QDialogButtonBox(QDialogButtonBox::Ok); ClosebuttonBox = new QDialogButtonBox(QDialogButtonBox::Close);connect(OKbuttonBox, SIGNAL(accepted()), this, SLOT(dis_sql_data()));connect(ClosebuttonBox, SIGNAL(rejected()), this, SLOT(hide_windows()));QGridLayout *mainLayout = new QGridLayout;mainLayout->addWidget(dateLabel, 0, 0);mainLayout->addWidget(DateEdit, 0, 1);mainLayout->addWidget(timeLabel, 0, 2);mainLayout->addWidget(timeEdit, 0, 3);mainLayout->addWidget(OKbuttonBox, 3, 0);mainLayout->addWidget(ClosebuttonBox, 3, 1);setLayout(mainLayout);简单的说就是相同的代码，使用debug编译的库可以正确显示，而使用release编译的库则会阻塞图形界面的线程，高手请指导，项目时间很紧，有哪位高手知道请多多指导，谢谢。
