See https://ghc.haskell.org/trac/ghc/ticket/8736. The current workaround for GHC 7.8 is to compile with -dynamic, not -dynamic-too.

That was it! Thanks so much.

Actually... not quite. -dynamic seems let ghci load, but when I load with the GHCI API, I get this: compile error: <interactive session>: cannot find normal object file ‘build/debug/obj/Util/Contro.o’ while linking an interpreted expression The proper name is 'Control.hs.dyn_o', so it looks like the suffix mangling code is getting confused. I must be doing something different than ghci anyway, because I have to pass -dynamic in the GHCI API to load, while ghci doesn't seem to need it. And of course ghci doesn't get the mangled filename. One thing is that I'm using '-osuf .hs.o', which is a bit confusing, since it should actually be '.hs.o_dyn', but there's no -odynsuf and I don't really know how all the name mangling in there works. I'll take a look in the ghci code to see how it's doing things.
