Which ghc is in your path? It sounds like Cabal is finding your old GHC and trying to read its package database, but failing due to http://hackage.haskell.org/trac/hackage/ticket/609
Does that sound right?
Thanks Ian
Yes, adding the new GHC to my PATH fixes the problem. It seems like that memory error is quite severe for trying to read a file with bad encoding—couldn't it fail with a simple "Bad encoding" exception or something?
I'm surprised by the memory error too. It may be a real bug. Would you mind reporting it, including the full output of 'ghc-pkg dump' for the GHC that was in your PATH in the above? Cheers, Simon
