GHC and GSL

Hi, I need to import in one of my programs the minimization module form Numeric.GSL.Minimization. When I run even the example code in interactive mode, ghci crashes with a "Bus error" message. Is this a bug, or is something wrong with my code? The offending program follows: module MinMaxTest where import Numeric.GSL.Minimization objFunc :: [Double] -> Double objFunc [x, y] = 10 * (x-1)^2 + 20 * (y-2)^2 + 30 main :: IO () main = do let (s, p) = minimize NMSimplex2 1e-2 30 [1, 1] objFunc [5, 7] print s print p I use ghc-7.6.3 on a Slackware-Linux platform. Can anyone help? Thank you in advance. Adrian-Victor
