A subclass with the extra functions is still the same implementation. (I guess QPingMessage is not a good recommendation as it would imply QObject inheritance). We can leave it.

Can you put the dump file on dropbox or google drive and put a sharing link here?

Not much useful in the call stack. I've no idea what to make of this.  @DonLakeFlyer is it possible to switch to Qt 5.9.4 or 5.10.0 for Stable 3.3?...

Wow that video is pretty impressive.
