[Qt-interest] Program crashing when I read quint32 from QDataStream

[Nicholas Shatokhin]

Look the code:


     quint16 compressionCode;
     quint16 numberOfChannels;
     quint32 sampleRate;
     quint32 averageBytesPerSecond;
     quint16 blockAlign;
     quint16 significantBitsPerSample;

     QBuffer buffer(&fileData);

     buffer.open(QIODevice::ReadOnly);

     QDataStream stream(&buffer);
     stream.setByteOrder(QDataStream::LittleEndian);

     stream >> compressionCode;
     stream >> numberOfChannels;
     stream >> sampleRate;
     stream >> averageBytesPerSecond;
     stream >> blockAlign;
     stream >> significantBitsPerSample;

     buffer.close();

Programs successfully read all data, but when it try to exit - it's  
crashing. If I change type of all variables to quint16 - it's works. If I  
change type of compressionCode to quint32 - it's writing message: "pure  
virtual method called
terminate called without an active exception"

What is wrong?
