 I have a project that depends on happy/alex to generate parsers.
 (https://github.com/TOSPIO/pyn)

 Running `cabal repl` on my laptop (Gentoo Linux amd64) with 16GiB memory
 ended up eating up all memory and eventually resulted in kernel panic.

 `cabal build` works fine. Problem arises when compiling the giant happy-
 generated dist/build/Language/Python/Parser/Parse.hs file

 also `cabal repl --ghc-options=-fobject-code` works fine.
