Comment (by ghorn):

 Here is another small test case:
 {{{
 {-# OPTIONS_GHC -Wall #-}

 module Main ( main ) where

 import Foreign.Ptr ( Ptr )
 import Foreign.Marshal ( malloc, mallocArray )

 main :: IO ()
 main = do
   _ <- malloc         :: IO (Ptr Int)
   _ <- malloc         :: IO (Ptr Int)
   _ <- malloc         :: IO (Ptr Int)
   _ <- malloc         :: IO (Ptr Int)
   _ <- malloc         :: IO (Ptr Int)
   _ <- malloc         :: IO (Ptr Int)
   _ <- mallocArray 10 :: IO (Ptr Int)
   _ <- mallocArray 10 :: IO (Ptr Int)
   _ <- mallocArray 10 :: IO (Ptr Int)
   return ()
 }}}
 This will fail as a bare-bones cabal project, but ghc --make will
 successfully compile it. I'm on GHC 7.6.3 on 64-bit Debian.
