Fix it by adding a non-inline virtual destructor to Channel.
Sure. It's just a pseudo code.
Then stop pasting pseudo-code. If you hide the problem, then you won't *see*
the problem.
Ok. I'm sorry.
In real code was virtual destructor and dynamic_cast and static_cast
worked, but qobject_cast failed.
The reason was in static linking of Channel to the application and to
the plugin.
You violated One Definition Rule of C++. Your application has Undefined
Behaviour. You caused this, you pay the price.
Stop violating ODR and it will work.
Yes, it's so.
