Terrible! Quite sorry that this seems to be a bug in the monad-par library.
I'm copying some of the other monad-par authors and we hopefully can get
to the bottom of this. If it's not possible to create a smaller
reproducer, is it possible to share the original test that triggers this
problem? In the meantime, it's good that you can at least run without
parallelism.
Here is slightly simplified original test case. By itself program is
very small but there is statistics and criterion on top of the monad-par
Failure occurs in the function
Statistics.Resampling.Bootstrap.bootstrapBCA. However I couldn't trigger
bug with mock data.
import Criterion.Main
test :: t -> ()
test _ = ()
main :: IO ()
main = defaultMain [ bench (show n) $ nf test () | n <- [0 .. 5000]]
P.S. I assume I've just got test failure report for the statistics from
your buildbot. Failures reported are spurious. Also linux box cannot
handle unicode in the output (wrong locale settings?)
