Comment (by dkwright):

 Happening for me with 2014.2.0.0 as well.  Loading this code (stripped
 down from something more practical), example.hs, in ghci and typing
 {{{main}}}, gives the error:
 {{{
 module Main where

 import Criterion.Main

 main :: IO()
 main = putStrLn "example"
 }}}

 Without the import of Criterion.Main, no error.  It looks like it's a
 dependency on ieee754 from Criterion.Main that does it.

 Error:
