Проблема с boost::crc_32_type, boost::crc_32_type Опции

[niXman]

Кто нибудь использовал се чудо?
У меня результат не сходится со стандартными утилитами.
Вот код:

        U32 crc = 0;
        const U32 DEFAULT_BUFFER_SIZE = 1024*32;
    boost::crc_32_type CRC32;
    
    char* buf = new char[DEFAULT_BUFFER_SIZE+1];
    
    QFile file( "any.bin" );
    Q_ASSERT( file.open(QIODevice::ReadOnly) );
    while ( !file.atEnd() ) {
        rd = file.read(buf, DEFAULT_BUFFER_SIZE );
        CRC32.process_bytes( buf, rd );
        
    }
    delete buf;
    
    crc = CRC32.checksum();
