System Information
Mac OS X 10.10.2, AMD 5770

Blender Version
Broken: 2.74.3 59df941

Short description of error
If you have a particle system with virtual parents above a certain threshold, and display % set below 100%, Blender will crash when you try to render the particle system.

Exact steps for others to reproduce the error

Load attached particle_disp_crash_2.blend
Hit F12 and note that Blender immediately crashes.
Reload the file, either turn virtual parents down/off, or change display % to 100%. Render again, Blender will now render successfully.

Developer note:

This is a mis-counting of child/parent particles in initialization and actual path calculation caused by mixed checks like (psys->renderdata || G.is_rendering) and psys->renderdata. I think we should get rid of this G.is_rendering in order to help new depsgraph as well. Here's a patch which is "works for me" (tm), but not sure what sideeffects it might cause: fix_T44268.patch

@LukasTonne, mind having a second look here?
