GHCi bug: bus error when executing some gsl-random code
When compiling this simple program, the resulting executable runs fine, while running it under ghci causes a crash. It's gsl-random related obviously, but the difference in behaviour between plain ghc and ghci is somewhat odd.
$ cat a.hs
import Control.Monad
import Control.Monad.MC
import Control.Monad.MC.Class
import GHC.Word
seed = 57
buildRow el l = (sampleSubset el l [1..]) `evalMC` (mt19937 seed)
main = do
mapM_ putStrLn (map show ((buildRow 2 10) :: [Double]))
$ ghc --make a.hs
