Re: Stack smashing when using FunPtr wrappers on ARM

24 Jan 2013


      I tried it here with android. It works, no segfault.
I have used llvm-3.2, maybe that helps?

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 ()
