There is nothing wrong with this patch that I can see.
It's pretty trivial to inspect.

I don't see the problem with this either.

There seem to be legit code coming out of umn.edu as well.
To me it seems like students getting assigned to fix random
NULL pointer dereferences, seems unfair that their first
contributions should be punished for what some researcher did.

But I would personally like to discuss the ethics of this
study with the headmaster of this university.
