QStringLiteral() would cause the application crash

In B.dll

    QCoreApplication::setOrgnization(QStringLiteral(....));

In A.exe

     Qlibrary library("A.dll");

     library.load();

     //  do something

     library.unload();

Then when close the application, the application would crash. This is due to a pointer to the memory in A.dll has been set to some values in QtCore.dll .
