Comment 18 for bug 1821909

Wow, I am unable to recreate this on Linux with any of the procedures above. This smells like a memory issue but my first guess (in #13) apparently didn't help.

The redraw is clearly referencing an invalid pointer. The fact that it only gets this invalid pointer after failing to remove a point indicates that the points vector isn't being handled correctly in the undo code that gets called after failure.

Valgrind isn't giving me any pointers here.

@Wayne- It would be helpful if you could get the type of item the viewgroup is trying to draw in your crash. I suspect it is the overlay but I could be offbase
