qPrintable(string) 

is actually just a macro that expands to

QString(string).toLocal8Bit().constData() 

The e-mail of qt-interest was about whether the temporary QByteArray created by toLocal8Bit() is guaranteed to be still valid by the time printf(...) is executed, and the answer (at the bottom of the thread) is that it is: It can only be destroyed after the whole statement has executed. So

printf("%s", qPrintable(x));

is okay while

const char * str = qPrintable(x);
printf("%s", str);

isn't.
