static void qt_message_fatal(QtMsgType, const QMessageLogContext &context, const QString &message)

the last argument is a QString, the message.

for an example see here

qobject.cpp:214

     if (Q_UNLIKELY(version != QObjectPrivateVersion))
         qFatal("Cannot mix incompatible Qt library (version 0x%x) with this library (version 0x%x)",
                 version, QObjectPrivateVersion);

This eventually calls qt_message_fatal() with a message like the string above, but it is discarded.
