Re: [Haskell-cafe] Regarding Haskell FFI

I think the fix eventually made its way into 7.4.1. This is the patch: http://hackage.haskell.org/trac/ghc/changeset/d146fdbbf8941a8344f0ec300e79dbeabc08d1ea Cheers, Simon On 28/03/2012 09:57, rajendra prasad wrote: Hi, I am using GHC version 7.0.4. Thanks, Rajendra On Wed, Mar
