CLDouble serialization bug in 6.10.1
Hello glasgow-haskell-users, sorry, i tested it only with 6.6 and 6.10.1. testcase available as http://www.haskell.org/bz/ldouble-bug.zip it's as simple as
foreign import ccall unsafe "" client :: Ptr CLDouble -> IO ()
main = with 1.0 client
and
void client(long double *p) { printf ("%f\n",(double)(*p)); }

I'm afraid GHC has never supported CLDouble properly. It's been removed from the HEAD: http://hackage.haskell.org/trac/ghc/ticket/2793 and there's a ticket to add proper support: http://hackage.haskell.org/trac/ghc/ticket/3353 If it's important to you, please add a note to the ticket. Thanks Ian
