I have strange behaviour when using QTemporaryFile. Temp files don't delete with this code when i exit from console program from Ctr+C or click on _[]"X" (Windows):

Qt Code: 
  1. #include <QtCore/QtGlobal>
  2. #include <QtCore/QtDebug>
  3. #include <QtCore/QCoreApplication>
  4. #include <QtCore/QTemporaryFile>
  5.  
  6. int main(int argc, char *argv[])
  7. {
  8.     QCoreApplication a(argc, argv);
  9.     QTemporaryFile file(QLatin1String("mytemp"));
  10.  
  11.     if (file.open()) {
  12.          qDebug() << file.fileName();
  13.     }
  14.     return a.exec(); // if i change this to "return 0;" all be ok
  15. }
To copy to clipboard, switch view to plain text mode 

and this code works fine:

Qt Code: 
  1. #include <QtCore/QtGlobal>
  2. #include <QtCore/QtDebug>
  3. #include <QtCore/QCoreApplication>
  4. #include <QtCore/QTemporaryFile>
  5.  
  6. static QTemporaryFile file(QLatin1String("mytemp"));
  7.  
  8. int main(int argc, char *argv[])
  9. {
  10.     QCoreApplication a(argc, argv);
  11.  
  12.     if (file.open()) {
  13.          qDebug() << file.fileName();
  14.     }
  15.  
  16.     return a.exec();
  17. }
