error in ghci calling main after loading compiled code -- Too late for parseStaticFlags: call it before runGhc or runGhcT

I  have a file mainbug.hs that consists of

main =
    print "hello"

I can reproduce it as follows:

 ghc -dynamic mainbug.hs
[1 of 1] Compiling Main             ( mainbug.hs, mainbug.o )
Linking mainbug ...
bash-3.2$ ghci
GHCi, version 7.10.0.20150123: http://www.haskell.org/ghc/  :? for help
Prelude> :load mainbug
Ok, modules loaded: Main.
Prelude Main> :show modules
Main             ( mainbug.hs, mainbug.o )
Prelude Main> main
Too late for parseStaticFlags: call it before runGhc or runGhcT
*** Exception: ExitFailure 1

Loading it interpreted works fine:

rm mainbug.o
bash-3.2$ ghci
GHCi, version 7.10.0.20150123: http://www.haskell.org/ghc/  :? for help
Prelude> :load mainbug
[1 of 1] Compiling Main             ( mainbug.hs, interpreted )
Ok, modules loaded: Main.
*Main> main
"hello"
