Short description of error
In this project I am working on I am getting nasty crashes repeatedly. This is about the sixth time tonight.
Sorry, but I don't have the know-how to narrow-down what is causing the crashes, however I will attach the .blend and an OS X crash report and hopefully it will offer some clues.

One thing I did note is that after a render my main object (a spider model) disappears from the 3D viewport.
Once the viewport is zoomed or a setting is changed that causes the viewport to refresh, either the object reappears or Blender crashes.
I have never had objects disappear like this before, so I believe this behavior is related to the crashes.

Exact steps for others to reproduce the error
Open the attached .blend and do some renders, change some settings, render again, etc. It shouldn't be long before it crashes.
May or may not be OS/hardware-specific.

Reduced file to cube with 17 hairs in particle system.
Steps to consistently reproduce crash.

  1. Select Particles panel, change number of particles from 17 to 18, hit enter.
  2. change 18 back to 17.
  3. render
  4. change size of 3D view window and crash.

(Changing particles to anything under 17 and back does not produce crash.)

Attached crash log and blend file.

FloridaJo, thank you for reducing the .blend to its very basic elements and reporting.
I used your .blend and was able to reproduce the crash on another Mac when resizing the window after rendering.
So now we have seen this occur on three different Macs running three different versions of OS X.
I wonder if any Windows or Linux users will be able to reproduce this.

Well, I'm on Linux :) Also note that we don't have to re-size the window, simply clicking in or trying to do anything with the 3D view will trigger the crash. It apparently happens in the function that draws the particles.

Kévin, thanks for mentioning that.
In my .blend I had the particles being influenced by an image texture, as well as by the particle settings. While these values should not step on each other's toes, it is something worth noting.

Crash in ILM lib again… :/ Anyway, seems related to particles.
