 I'm trying to compile a pronunciation dictionary (cmudict) into an
 application. I'm first converting the dictionary into haskell source, and
 then trying to compile it.

 After about 7 minutes of compiling, ghc's memory usage was in the
 gigabytes and causing the computer to start heavily swap.

 Attached is self contained generated source file.
