 32bit GHCi on Mac causes segfault/panic:

 With GHC 7.6.3:

 {{{
 > :m Data.Complex
 [Prelude Data.Complex]
 > ((-2) :+ 0)**(1.5 :+ 0)
 zsh: segmentation fault  ghci
 }}}

 With GHC head:

 {{{
 > :m Data.Complex
 > ((-2) :+ 0)**(1.5 :+ 0)
 ghc: panic! (the 'impossible' happened)
   (GHC version 7.7.20130805 for i386-apple-darwin):
         Loading temp shared object failed:

 Please report this as a GHC bug:  http://www.haskell.org/ghc/reportabug
 }}}

 64bit GHCi does not cause this problem. Any GHCi on Linux and FreeBSD do
 not cause this problem.

 If the code is compiled with 32bit GHC on Mac, it works fine.
