-fext-core -fno-core behaves funny

Suppose I have a module Main.hs which I have already
compiled, which means I already have Main.hi.

Now I compile it again with the flags -fext-core and
-fno-code. What happens now is that ghc says:
compilation IS NOT required

and generates an a.out (!) but not a Main.hcr.

Now this really surprised me. I expected that no a.out
should be generated (since I give the -fno-code flag)
but that Main.hcr still should be generated.
