---------------------------------+------------------------------------------
On OS X 10.6.6, GHC API causes bus error when it is used from
ghci/runhaskell.
Minimal case (ghc-api.hs) is below:
{{{
import GHC
import GHC.Paths
main = do
runGhc (Just libdir) $ do
getSessionDynFlags >>= setSessionDynFlags
dynCompileExpr "()"
}}}
Run it by "runhaskell", then bus error was occurred.
We can also cause same bug using GHCi as below:
{{{
Prelude> :m GHC GHC.Paths
Prelude GHC GHC.Paths> runGhc (Just libdir) $ getSessionDynFlags >>=
setSessionDynFlags >> dynCompileExpr "()"
