!!!A Strange Crash

[high_flyer]

it could be that due to configuration issues, your image is not found, and thus you get a null pixmap.
Try this:

XXXSplashScreen splash; //XXXSplashScreen encapsulate the QSplashScreen
if(splsh.pixmap().isNull()){
  qDebug()<<"nuill pixmap";
}
 
splash.show(); //the program crash right here
app.setWindowIcon(QIcon());

XXXSplashScreen splash; //XXXSplashScreen encapsulate the QSplashScreen
if(splsh.pixmap().isNull()){
  qDebug()<<"nuill pixmap";
}

splash.show(); //the program crash right here
app.setWindowIcon(QIcon());

To copy to clipboard, switch view to plain text mode 

and see if the debug message comes out, or you can set a break point on the debug message.
