I see now what this bug comes from. It's from foreign imports that
use the wrong IO. So it's not correct code that's being flagged here,
but it's also a pretty unhelpful error message for the case where a
foreign import is declared with an inappropriate type.

Hi John,
I'm getting the following failure, which looks to me like a compiler bug. I've cleared my cache, and rebuilt jhc from scratch, so this time I think it's a real bug.
Compiling... [ 1 of 13] System.C.Stdio user error (lookupExtTypeInfo: (ELit ((#2#) (ELit (Jhc.Prim.World__::ESort #)) (ELit (Foreign.C.Types.CInt::ESort *))::ESort #),ELit ((#2#) (ELit (Jhc.Prim.World__::ESort #)) (ELit (Foreign.C.Types.CInt::ESort *))::ESort #)))
The code is unfortunately somewhat large. You can (once again) get it at
darcs get http://abridgegame.org/concurrency
You can either build it using a very recent franchise and ./Setup.hs configure --jhc, or you could use the attached base-alt.config, and compile with something like
jhc -ijhc -ibase -ialt --noauto -isrc --dependencies base-alt.jhc-deps --build-hl base-alt.config
As you may be able to gather, I've not yet been able to kick the habit of hacking on jhc's library.
It's possible that this error is due to a bug I've introduced (I certainly introduced plenty along the way), but since it type checked, I think it ought to succeed in the compile stage. -- David Roundy
