%%%--- Operating System, Graphics card ---
Win 7 x64, Nvidia GTX 550 Ti
Win 7 x64 ATI Radeon HD 4800 (only 56305 build tested)

- Blender version with error, and version that worked ---

daily build 56305, 56100, 55211, official 2.66a
CPU render, experimental feature set.
(test file was created in 56305, and then opened and crashed in the older versions)

- Short description of error ---

I tried to track down what exactly causes the crash, but couldn't. It seems that it stops crashing when I decrease the complexity of the scene in any way. But the memory usage is not that high. In the test scene, it crashes at Mem = 327.06M, the highest Mem I noted during a crash of a similar scene was about 2000M.

The attached scene crashes always, on both systems I tested.
The crashes started around the time when I put hair onto one of the objects, but they continued after I switched the hair off.
When I switch Object Data > Displacement > Method > to Bump for the object "trees_front.001", it stops crashing.
When I leave Displacement Method = Both, and delete all objects except for lights, camera and "trees_front.001" (which is the most complex object in the scene), it stops crashing.
When I delete "trees_front.001" and leave all other objects in the scene, it stops crashing.
When I remove all textures from the materials (editing each material nodes tree), it stops crashing.
When I override all mateirals by a gray Diffuse BSDF (Render Layers > Material), it stops crashing.

- Steps for others to reproduce the error (preferably based on attached .blend file) ---

The file is here (I'm sorry for the size, but smaller versions don't crash):
http://www.ania.xibo.at/tmp/animation_e_crashtest_no-hyrax.blend
Open the file, press F12 -> crash
It crashes at some point of the render calculations, in this case before it starts doing buckets.
Other versions of the file sometimes crashed after rendering half of the buckets, or sometimes it rendered one animation frame and crashed at the second frame (which was the moment that a hyrax jumped into the scene, increasing the scene complexity by its hairy presence).

%%%PS.
Strangely, no test scene crash with GPU render.
Which sadly won't solve my problem, because my GPU doesn't have enough memory for rendering my "real" scene. %%%

%%%It's the displacement feature that crashed, somewhat random because it was accessing uninitialized memory. Fix in svn, thanks for the report.%%%

%%%Thanks!
Now it's stable also in the bigger scene :) %%%
