I set the tags due to the fact that the fall is only when the result is returned. But this may be a false suspicion.

I can not reproduce it in f0e1089a33. Using a Linux system.

Can not reproduce either (checked in current master)
Last two steps are not really clear to me. What exactly I've to repeat?
@mod_moder, could you verify the crash with factory settings?: {nav File > Default > Load Factory Settings}

I repeat only undo and redo. Many times.
Hiding sockets is just for compactness. But the result is not affected.

Can't reproduce either. Can you share the crash stack trace?

Potentially 6c4b72b135 fixed it. Although I'm not sure if I can reproduce this in older versions as well. Since no one was able to reproduce it, and also I now (although there may be a new Windows involved) I will close it.
