This bug disappears if you compile cabal-install with GHC 6.12.1.

I suspect recompiling with any version would work. If we cannot reproduce this there's not a lot we can do. If it can be reproduced then please post details here.

I have reproduced on 3 machines. Install GHC 6.10.4. Install Cabal binary from the website. Run cabal update. Run cabal install cabal-install. Observe that cabal update no longer works.

This is what confused me. I now assume that this comment was a mistake.

I confirmed a bug in cabal-install-0.8.0 on Windows. The update always fails because of a bug in how the downloaded file is written. The fix is in the darcs version (0.8.x branch) and will be in the 0.8.2 release.

If anyone thinks my diagnosis is wrong then please re-open.
