Usually, a bus error is similar to a segmentation fault, in that it indicates something has gone terribly wrong. However, as hmatrix is an API to some foreign C libraries, I would not rule out the possibility that it's a bug in the library itself. What version of hmatrix do you have, and if you compile the program with -debug and run it in gdb, do you get a backtrace?

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
