Hi Thorkil, I looked at this code a few days ago, and I really couldn't figure out what was going on! As far as I can tell: Package.hs, line 64: case (local,res) of ([x], _) -> return x (_, [x]) -> return x ([], []) -> raiseError $ ErrorFileNone noErrPos askMsg file rs (as, bs) -> raiseError $ ErrorFileMany noErrPos askMsg file (map anyOne (as ++ bs)) The basic idea is that local and res are the local findings of a module, and res are the remote findings of a module. If there is one local module that comes first, if there is one remote module that comes second. If there are no modules this raises an error. The final branch is that one of as or bs must have a value. Your patch makes the last case demand (:) for both arguments - since case statements in Haskell match top to bottom, that means you'll just end up with a crash otherwise. The actual property is that one must be non-empty, not both. I really couldn't see what this is failing, but I'll have a quick Debug.Trace fest later. Thinking about it, if you have multiple local files, and one remote file, that makes it succeed. That's the wrong behaviour! I'll try and fix that while I'm there.

Recursively Dependent Modules
by Andrew Wilkinson 23 Feb '07

23 Feb '07

Hi, I've been trying to fix the dependency issues introduced through the changes to Control.Exception and we've got a loop in the dependencies. How should I handle this? Foreign.C -> System.IO -> System.IO.Error -> Control.Exception -> Data.Array-> Numeric -> Foreign.Word -> Foreign.C.Types -> Foreign.C a -> b means that b depends on a, i.e. has b an 'import a' statement.
