Sorry, I couldn't find any crash log in my temp folder.

So I launched blender from cmd, and tried to cause this crash.
Then I got messages below.

C:\Program Files\Blender Foundation\Blender>blender
Read new prefs: C:\Users\ysksa\AppData\Roaming\Blender Foundation\Blender\2.78\config\userpref.blend

read blend: C:\test\render.blend

(I pushed "Render" button at this point)

Error: EXCEPTION_ACCESS_VIOLATION

Crashes in RE_addRenderInstance(), when retrieving 11th child particle (part_index = psys->child[obi->index - psys->totpart].parent; with obi->index == 20 and psys->totpart == 10).

Think this is a problem between preview and render number of childs, here clearly the 10 first ones are OK, but not beyond (file is set to 1 child per particle in preview, and 10 per particle in render)… Still digging to try to understand that mess better.

There is nothing related to data being linked actually, as you can see in attached file below, it's enough to instantiate a group with dupliob particle system, and then hide (on another layer e.g.) original objects of the group…

Still trying to figure out a fix for this mess…

I've tried to use today's daily build. It doesn't crash!
I'm very happy. Thanks for your work!
