[Solved] Crash in Release-Mode Visual Studio

zweistein

Hello,

QT 4.8.3 seems to be installed wrongly. It works perfectly on two of my computers, but it doesnt work on my third computer. Everything compiles fine, but when i run this code in release it crashes. In debug mode it works perfectly. In release mode it compiles and runs, but when i CLICK on the combobox it crashes!

@
#include <QApplication>
#include <QGLWidget>
#include <QGraphicsScene>
#include <QGraphicsView>
#include <QComboBox>

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

QGraphicsScene scene;
QGraphicsView view;
view.setScene(&scene);

QGLWidget gl;
view.setViewport(&gl);

QComboBox c;
c.addItem("test");
scene.addWidget(&c);

view.show();
return app.exec();
}
@

This is a minimalversion of the crash.

Compile:
configure -debug-and-release -opensource -qt-zlib -qt-libpng -qt-libjpeg -qt-libmng -qt-libtiff -mp -no-webkit -no-phonon -no-phonon-backend -no-script -no-scripttools -no-qt3support -platform win32-msvc2010
nmake

System: VS2010 64bit, Windows 7 64bit, Xeon E5-2680, Geforce GTX 680

Problem fixed.
Never compile QT with Visual Studio 2010. Period. It is buggy!
You have to use Visual Studio 2010 Service Pack 1 /and/or the hotfix...
