 When running the supplied code in GHCi, it crashes out with the error
 message "internal error: interpretBCO: unknown or unimplemented opcode
 64956". The opcode seems to vary between 64956 and 64949, but possibly
 others. The crashing is consistent though. The code compiles and runs fine
 with GHC. It also runs fine on a Ubuntu linux system (albeit slow, which
 is to be expected) which I have access to.

 The code is taken from a university coursework assignment, and generates
 minimax labels for a tic-tac-toe game tree. It is a cutdown version of the
 full program, with only the code required to expose the bug present.
