for some reasons Chrome didn't upload the *.blend file, so I link it here.

I checked it in win 7 gtx 550ti in master, release, and my own build it works fine without freezing.

To Devs: I m commenting here because i m having some kind of random slow down in my complex huge scene (appends, links, particle, multires, trees, ...) that makes Blender to randomly freeze and they are really difficult reproduce. I have been tracking the slow down since 09-may i have a build hash 98e2135 that works really good and every time the latest build freeze with a give operation, hash 98e2135 preform really good.

Sorry for the noise.

Most likely same issue as in T48422, please try again with latest testbuild, should be fixed.

Cant redo with/without rB98123ae91680289255f5fa6cf6ae0ff6dcba251b (compared with latest master) and can't redo on 64-bit Linux.

I m still getting some random crashes with 22d53e5, this time it crashes when rendering, but hash 98e2135 is rendering the scene now. i really don't know how to help here :( May be it will be better to start my own report so we can investigate together.

@Erick Tukuniata (erickblender) yes, please do own report, don’t think it’s related to that one, which I’ll consider fixed for now.
