Description

During migration to g++ 12 I hit the warnings reported in ~~QTBUG-105388~~. After upgrading to Qt 6.5.0 those are gone, but I still get one warning (multiple times from multiple locations in my code, this is one stack example but always on qhash.h:561):

In member function '__ct ',
    inlined from 'detached' at []/include/QtCore/qhash.h:577:20,
    inlined from 'detach' at []/include/QtCore/qhash.h:941:75:

      |                          ^

This is using Qt 6.5.0, g++ 12.2.0 with LTO enabled.
