Stack smashing when using FunPtr wrappers on ARM

24 Jan 2013

      I just got my unregistered LLVM-based ARM cross-compiler to a working place, 
which means I can produce any binaries which do no crash.  Yay!

However, http://hackage.haskell.org/trac/ghc/ticket/7621 when I try to use 
FunPtr wrappers, something smashes the stack.

Would others working on ARM cross-compilers be willing to try this test and 
see if it works for you:

{-# LANGUAGE ForeignFunctionInterface #-}
module Main (main) where

import Foreign.Ptr

foreign import ccall "wrapper" wrap_refresh :: ( IO ()) -> IO (FunPtr ( IO ()))

main :: IO ()
main = do
	wrap_refresh (return ())
	return ()
