- Ton,
I really dont have much time nowadays.

- How to reproduce from scratch:
1. Start Blender
2. Add new mesh (e.g. Plane)
3. Add new material
4. Add new texture
5. Enable "Normal" and "Displace" at texture panel
6. Enable "Mirror" (and "Transparency", if necessary) at material panel
Then, Blender should crash with the above error message.
Confirmed with r34641.

- @Andre
I attached "simple_crash.blend". I can reproduce the crash if I open it and just click the "Mirror" and "Transparency" check boxes.
My evnironment is:
* OS: Ubuntu 10.10 amd64
* CPU: Core i7 870
I also tested in VertualBox and can reproduce it there:
* OS: Ubuntu 10.10 i386
* Enable only single core
If you have Ubuntu 10.10 box, you can test my Blender's binary by installing from my PPA:
https://launchpad.net/~irie/+archive/blender
I applied some patches to the binary in this PPA, but they shouldn't affect this issue because I can also reproduce using another binary built without the patches.

- Hehe no problem with the typos :p
Hmm well I tried that bug on the day repository was down, so i was using gitorious copy, which was only in rev34520.
Apparently that doesn't crashes on that version.
Well I am compiling the latest trunk now...
Hmm i tested on my

- Thanks Shinsuke, your scene was pretty useful :)
If anyone needs to render stuff for now: Try change the bumpmap mode to: original or compatible.
I think it should fix it.
I will try to hunt down why the other options lead the creation of VlakFaces that don't really exist (eg.: dont have bounding box)
And my assert was catching that.
I think this is the commit related with the crash:

- here's the (so far) most simple way to reproduce:
new plane + material + texture
map texture to normal + displace
set bump method to default or best quality
set bump space to viewspace
couldn't get it to crash in any other bumpspace,
but noticed the following:
displace has no effect in the new bump methods.
since André seems to lack time, I'm on it :)

- The issue was that displacement calls the texture system without derivatives.
I added a fix for this. Let me know if it still fails!

- Closed duplicate [#26035], includes mesh example, perhaps useful to test as well.
re-opening.

- Initially posted file (group-particle-crash.blend) still causes crash. The new example [#26035] also uses the particle system for water drops.

- Closing this report (because it's fixed). The other report is a real BVH problem.
