Some old NaN checks in character movement use checkf() which will crash, those should be ensures. Other code is inconsistent in using either ENABLE_NAN_DIAGNOSTIC (with side effects), and some users would like to see the more important ones just use ensure or done in non-shipping without having to turn on that flag.
There's no existing public thread on this issue, so head over to Questions & Answers just mention UE-27693 in the post.
