**System Information**
MacBook Pro OSX Mavericks
**Blender Version**

Modifying hair emission number to a value of 800 or greater causes crash.
**Exact steps for others to reproduce the error**
1. Open attached blend.
2. Select the Sphere object, and switch to Particles panel.
3. Change Emission Number 800 or 1000 (seems to be anything over 800 on my machine).
These steps crash every time on my machine.
