Unity crashes on building project

Hi Guys

I’m having a big problem with building my project:
I got 3 levels in my project and whenever I try to build it (Unity Standalone for Windows x86), Unity crashes while building level 2.

Yesterday it still gave me a “system out of memory-error”, but today it just crashes without any dialog box popping up…
Here is the last part of my log-file:

The tree Rock6B must use the Nature/Soft Occlusion shader. Otherwise billboarding/lighting will not work correctly.

tlsf_create: Pool size must be between 3208 and 1073745020 bytes.
Crash!!!

I’m really a beginner so I don’t really know what to do and I would be very grateful if you could help me!

Thanks

—Edit—

Thanks for your answers! Now that’s bad news, I’ve got a deadline in two weeks! Does anybody know what that last line “tlsf_create: Pool size must be between 3208 and 1073745020 bytes.” means? I guess that this is causing my crash, so it shouldn’t be impossible to solve the problem, right?

This is most likely a bug with unity that you should report.
Nothing I can do.

Awesome! I pre-ordered Unity 5 and as you may know, it is a 64-bit application! The Editor now builds without any problems!
