float constant dumps core

ghci dumps core if I enter a floating point constant in
any expression:

  Prelude> 1.0
  Illegal instruction (core dumped)

Any program compled by ghc which contains a floating
point constant dumps core in the same way if/when the
constant is evaluated (but it does compile OK).

Coercion from integer to float works in both ghc and
ghci:

  Prelude> 1 :: Float
  1.0
