Unhandled exception at calling overriden function

[LPeter1997]

Hi!
I can't even make a guess what could be the problem here.
I think it is easier tho show a video:

I think it describes my problem. I don't know what's my mistake! The debugger doesn't really help, I don't use malloc or free.
What could be the problem?

Please describe your problem in some sentences and maybe with a code snippet. Your videos image is very diffuse.

One would've suspected that with your gratuitous use of new.

The problem is that you are accessing memory you don't own, so look for pointers that contain addresses for objects that have gone out of scope (i.e. invalid objects) or variables which are uninitialized.

@cire, op: I couldn't identify anything on the video. It was very cloudy. I could imagine a computers mouse hovering over a computes window. But thats all. Sorry, but our German internet connections aren't really the most powerful ones.
