Are you compiling with aggressive cross-module optimisations on (e.g. -O2)? You may have to add explicit inlining pragmas (check the Core output), to ensure key functions are exported in their entirety. -- Don _______________________________________________ Glasgow-haskell-users mailing list Glasgow-haskell-users@haskell.org http://www.haskell.org/mailman/listinfo/glasgow-haskell-users
