initializeWorld = (\w -> do
                 worldSetGravity w 0 (-1.0) 0
                 worldSetERP w 0.2
                 worldSetCFM w 1e-5
                 worldSetContactMaxCorrectingVel w 0.9
                 worldSetContactSurfaceLayer w 0.001
                 worldSetAutoDisableFlag w 1),

 these worldSet* functions are unsafe FFI calls. initializeWorld is Ptr Int
 -> IO ()

 commenting this prevents this bug. this code is found in a top level
 declaration:

 initiailLevel = Level {
  ...
 }

 of which contains the record for initializeWorld
