It appears to be related to the MeshSequenceCache modifiers on the flag objects. When I remove those modifiers, the crash no longer occurs.

I can confirm that it does not seem to happen on Linux. I testet it on my old laptop, which is windows/linux dualboot. On Windows it crashes, with the same crash file as in my first report. On Linux it does not crash.
