I just do this:
for(r=[1:9]) {
  translate([10*r,0,0]) sphere(r);

It will build progressively larger objects and with the cache debug output it's easy to see where the cache fails.

> BTW, about the crash I had. I ran it through gdb and apparently OpenSCAD is terminating with SIGKILL and I get no back trace or core dump. Does that mean the OS is killing it? I really don't know what's going on here because I rendered the model just fine with the exact same settings on a different machine. They are both Ubuntu 11.10, but it crashes on a 64-bit machine and works on a 32-bit machine. Running the latest code on both. Any ideas?

No idea, but it sounds a bit fishy that it crashes on a 64-bit machine. I don't have a 64-bit Linux box available.
Has anyone else seen such behavior?
