In your dynamic hair test render?
Are U using a Raytraced shadow on a light? ?

Prediction;
The render will finish, (sooner or later) but PP2014 will "hang" at the end of the render, and some buckets will not render to screen.

It will not crash (hopefully) but it will "hang" requiring a forced close down.
