I'm using ghci + hmatrix and a few other packages as a Haskell based replacement for Matlab, everything works well so far in terms of available functionality. However, I have encountered an issue when running in ghci on x86_64 systems - calls into functions that in turn call gsl functions will result in a bus error, e.g: Prelude> :m +Numeric.Container Prelude Numeric.Container> randomVector 10 Gaussian 10 fromList Bus error (core dumped) I attached gdb and found the bus error was happening in gsl_rng_alloc() but some investigation indicate that the problem is probably due to this bug in ghci: http://hackage.haskell.org/trac/ghc/ticket/2912 which has been marked as a duplicate of http://hackage.haskell.org/trac/ghc/ticket/781 and a recent update to 781 indicates that it won't be addressed until at least v 7.6.1 (781 also references http://hackage.haskell.org/trac/ghc/ticket/3658 and it seems that this is a pretty large piece of work - moving to fully dynamically linked ghci which has been around for a while and pushed back a few times). Does anyone know of a workaround that would allow ghci to use wrapped gsl functionality on x86_64 systems in the meantime? Most linux boxes used by quants are x86_64 now, so this issue will impact many people who would like to use Haskell instead of Matlab. Thanks
