I am using GHC 6.12.3
Here a reproduction:
in the file Template.hs
proc () = runIO $ do runQ [|1+1|]
proc' () = [|1+1|]
In the file Main.hs

fault/access violation in generated code". Maybe is it the expected
behavior, I

Lame me, I found the answer here:

ghc -osuf p_o -prof -auto -auto-all -fforce-recomp --make -cpp -O

That seems like a fairly extreme thing to want to be doing... But yeah,
if you wanted to do something like that, machine-generated is the way.
