**Macpro 4,1**
Operating system and graphics card:
Mavericks OS X 10.9.4 (13E28)
2x GTX 590 cards
**2.71**
Broken: Rendering with GPU (as above video cards) Get out of memory error - when I use 2.7 on very same scene it renders fine. Also preview rendering same problem and same on 2.7
Error details:
Scene gives 645.92MB Peak memory when rendered successfully on 2.7.
Scene gives 2642.2MB Peak memory when fails on 2.71
Note: The scene is relatively complex.
Note2: I have previously managed to render an earlier version of the scene by a complete reboot and then render the scene immediately.
