Hi,

I just have found in my code string like this: 

QString str = QString().setNum(1234);

This can be replaced as:

QString str = QString::number(1234);

I checked Qt's source code and setNum() uses number() inside anyway. I assume
calling setNum() like this should be case for "qstring-allocations".
