Blender crashes when I change the particle amount from 2142 to a higher value in the attached file.
The crash does not occur if I change this value after having set the current frame to 0.
I'm running blender 2.56 r34172 on a Linux x86_64.
Here's a backtrace :
Program received signal SIGSEGV, Segmentation fault.
