A reference is ok. The problem is the copy or move, since now the object's this no longer points to the dummy member inside the QObject-derived class, but to somewhere on the stack. Then that UB pointer manipulation begins reading garbage and making matters go from bad to worse. -- Thiago Macieira - thiago.macieira (AT) intel.com Software Architect - Intel System Software Products _______________________________________________ Development mailing list Development@qt-project.org https://lists.qt-project.org/listinfo/development
