That's probably a problem(?) in Criterion.
If you move the functions you want to benchmark to their own module, 
compile that with -O0 and then compile the benchmarking programme with 
optimisations, it works properly.

I always put the functions to benchmark in their own module and compile 
separately to prevent GHC from performing optimisations which it only does 
within one module (and possibly for non-exported functions).
Who would've thought that is also necessary with -O0.
