Strange. I'm playing this under Linux, and I never got this particular issue. The only thing I have ever gotten was a GC get thread context failed or something like that error.
Granted, the Nvidia drivers for Linux are rather iffy, especially around intense 3D stuff or power saving stuff.
EDIT: Wait, Mac OSX uses some weirdo hypervisor thing, part of it based on some offshoot of BSD right? This mean that SIGABRT would be a valid signal in OSX, right?
