HD cache calculations freeze + crash

[maru]

Just downloaded newest build (Build timestamp: May 25 2014 19:59:58) and this happens: I created a simple scene with a room with a window hole, when rendering pt+pt everything is ok, when I switch to pt+hd and hit RENDER, the rendering freezes at the very beginning of HD cache calculations and doesn't continue. When I hit cancel, whole max's interfaces is frozen and I have to kill it manually. After some experiments I've come to conclusion that this doesn't happen only when there is no portal covering the window hole. If the portal is a bit smaller - it renders fine. If I make it big enough to perfectly fit the window hole - it crashes. Scene in attachment.
