Bizarre. There doesn't seem to be any significant difference in the seg
code between 8.2 and 8.3, so why is 8.2 failing there?

The cube code got a significant overhaul (V0 to V1 call conventions)
between 8.1 and 8.2, so that might explain why it's OK in 8.2 and up.
Or not. If that is it, we'd likely just write it off as not-gonna-fix,
but it could stand investigation to pinpoint the cause.

Can you poke into it with a debugger? The first failure case in seg
ought to be easy enough to investigate.
