Material editor crashing my machine sometimes

What steps can I take to reproduce
this error on my end?

As I’ve said above, I was tweaking parameters in node networks in the material editor. I was playing with opacity, ways to boost the subsurface scattering effect etc in a tree’s leaves, which was using the foliage shader model.

Now, in a blank project I…

  • Created a material
  • Opened material editor
  • Loaded a perlin clouds texture (jpg)
    I’ve made here in a Texture Sample
    node
  • Then I plugged a Panner and a
    Rotator in it.
  • Then (as I didn’t learn yet how to
    use the Rotator properly) I plugged
    the output from the Panner to a
    BreakOutFloat2Components, trying to
    plug the Rotator only in the X
    coordinate output to see what would
    happen
  • Then a MakeFloat2, to plug it again
    in the input of the Texture Sample…
    While tweaking parameter values… it
    crashed

Well, randomly trying things which I think would press the shader compiling to crash.

Thanks in advance,

Edit: Just to help spot it, I have “Live Preview” and “Stats” enabled in the material editor’s top bar/shelf.
