System Information
Operating system and graphics card

Blender Version
Broken: (example: 2.69.7 4b206af, see splash screen)
Worked: (optional)

Short description of error

Exact steps for others to reproduce the error
Based on a (as simple as possible) attached .blend file with minimum amount of steps

I am using Blender GIT Rev GIT2014-04-18-15-11-20-5a3fbc8 on a Fedora 20 Linux 64 Bit
Linux box with an Intel 3000HD GFX.

I have attached my system-info.txt and backtrace and a blend file that uses
Blender Game Engine. Pressing P on opening the file will seg fault Blender
when the alien space ship move across the screen.

This doesn't segfault on the official release but does on my builds and the most
recent build from builder.blender.org (Fri Apr 18 02:07:59 2014)

Does not crash here, but after a few seconds Blender freezes… Mitchell, another one for you. :)

There are actually two issues here. The crash comes from occlusion culling (this can be disabled in the world properties as a work-around for now). The freeze @mont29 describes is caused by multi-threaded animations. I'm investigating a fix to this.
