You might try running science-test.rkt multiple times and see if it fails. It's the simulation collection where I see the problem mostly. It uses the differential equation solver from the science collection, which is the only place I know of that uses boxes, but there may be others. I was using Windows 7 64-bit today when I tried it. I'll see if science-test works for me.
When it does fail for me now, it is consistently with a seg fault in gc. I'll keep checking nightly builds on my home machine in the evenings. I'll look into the unsafe-fl* error.
