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):

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.
