 If ~/.ghci is set to load some module when startup, GHCi sometimes raises
 SEGV.
 "Sometimes" means that ghci sometimes launched successfully and sometimes
 not. So please try it more than three times.

 Below is the minimal .ghci file to reproduce the problem:

 {{{
 :m Prelude
 }}}

 I use virthualenv package to use GHC-7.4.1RC. I installed it as below:

 {{{
 $ wget http://www.haskell.org/ghc/dist/7.4.1-rc1/ghc-7.4.0.20111219-x86_64
 -apple-darwin.tar.bz2
 $ virthualenv --ghc=/***/***/install/ghc-7.4.0.20111219-x86_64-apple-
 darwin.tar.bz2
 }}}

 Used virthualenv package is built on GHC 7.0.4.
