I've seen this warning now on both signals and slots and since our code isn't crashing this seems like a reasonable explanation and needs special attention.

I know it is happening with the newer connect style, I can't remember if we had an example using the older style.

With this statement the special treatment should extend to more than signals and slots and if in a connect then maybe suppress

https://wiki.qt.io/New_Signal_Slot_Syntax

It is possible to connect to any member function of QObject, not only slots.

With --library=qt, I don't get the pureVirtualCal warning. Otherwise, I do.
