Comment (by osa1):

 Great analysis @sighingnow.

 You don't actually need the map, here's a simpler reproducerL

 {{{
 $ ghci
 GHCi, version 8.4.2: http://www.haskell.org/ghc/  :? for help
 Loaded GHCi configuration from /home/omer/rcbackup/.ghci
 λ:1> [9007199254740990..9007199254740991] :: [Double]
 }}}

 This prints an infinite list.
