Sorry, I forgot about this thread. Do you still have this problem?

Regards, David Yea, i haven't tried to fix it since then though. I took a look at this problem again, and I think I nailed down to a GHC bug (but you can never be sure):

http://hackage.haskell.org/trac/ghc/ticket/3008

David Thanks for looking at it again.

I tried passing -O* to ghc through haddock but it doesn't seem to do anything.

I know! I was also confused by this. But it could perhaps have something to do with the fact that Haddock doesn't compile anything, at least if you're using one of latest versions :) So, I hoping for htis to be a GHC error.

For the mailing list's reference: --------------------------- 02/12/09 01:25:40 changed by simonpj Excellent report. The real culprit is in the FFI spec: see http://www.haskell.org/pipermail/haskell-prime/2009-February/002726.html. Until that thread is resolved, you can work around this bug by exporting GL(..). Indeed, if my proposal is accepted, you'll be forced to do that. Simon
