Comment (by hkBst):

 I don't know if this is related or not, but after compiling with profiling
 enabled:

 $ ghc -O2 -fforce-recomp -prof -fprof-auto tinychess.hs

 even

 $ $ time ./tinychess 0 +RTS -p

 would exhaust memory on my machine and I had to kill it.  The argument 0
 determines the depth of moves that are considered for evaluating the
 possible next positions.  Without profiling this completes instantly as
 one would expect.
