Periodically, I build the CogVM from source on FreeBSD. I've prevously mentioned that I had encountered some oddity with FFI on that platform. Still there today.
The following code crashes the VM/image:
The oddity is that one particular version of the SqueakFFIPrims plugin works. Several other versions that I've built all fail. Overwriting the failed versions of the plugin with the known-working one allows that particular crashing VM's FFI to work.
The working one appears here three times. I'm running FreeBSD 8.3.
