| Subject: <<loop>> reading in external Core
| 
| There seems to be a bug in the latest version of GHC involving
| renaming/typechecking external Core files (well, besides the last 3
bugs
| I posted about...):
| 
| 
| $ ghc -fext-core -fno-code Hello.hs
| /home/deforest/ghc6.1src/fptools/ghc/compiler/ghc-inplace -fext-core
-fno-code Hello.hs
| $ ghc Hello.hcr
| /home/deforest/ghc6.1src/fptools/ghc/compiler/ghc-inplace Hello.hcr
| ghc-6.1: panic! (the `impossible' happened, GHC version 6.1):
|         <<loop>>
| 
| Please report it as a compiler bug to
glasgow-haskell-bugs@xxxxxxxxxxx,
| or http://sourceforge.net/projects/ghc/.
| 
| $ cat Hello.hs
| cat Hello.hs
| module Hello where
| 
| foo = putStrLn "Hello world!"
| $ cat Hello.hcr
| cat Hello.hcr
| %module Hello
|   foo1 :: GHCziIOBase.IO GHCziBase.Z0T =
|     SystemziIO.putStrLn
|     (GHCziBase.unpackCStringzh ("Hello world!"::GHCziPrim.Addrzh));
|   Hello.foo :: GHCziIOBase.IO GHCziBase.Z0T = foo1;
| 
| I get the <<loop>> message with every .hcr file I've tried
(restricting it
| to ones that don't define a "main" function, due to the issue
mentioned in
| my previous post). This is with a GHC built from sources downloaded
from
| CVS today. If I try to narrow things down by adding various verbosity
options,
| the error message gets printed right after the renamer stats get
printed out;
| that's as much as I've been able to figure out.
