 I load a trivial module via the API. I get a panic:
 GHCBugs.exe: GHCBugs.exe: panic! (the 'impossible' happened)
   (GHC version 7.4.1 for i386-unknown-mingw32):
         mkNoTick: Breakpoint

 If I pass -O2 in the options. Without -O2 the module loads.

 I attach the source code using the API to the ticket. The module I try to
 load just says:
 module Main where

 main::IO()
 main = print "Hello Fay"
