You can replace: {{{#!haskell foreign import ccall safe "test" c_test :: Ptr Word32 -> IO () }}} with: {{{#!haskell {-# NOINLINE c_test #-} c_test :: Ptr Word32 -> IO () c_test ptr = poke ptr 0xDEADBEEF }}} -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14346#comment:13 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
