 Using the newest library version on hackage, "cabal update" segfaults
 after downloading the package list from hackage. "cabal install" produces
 the error
 "cabal: Data.ByteString.Lazy.index: index too large: 0"

 steps to reproduce the problem (at least for me): install the newest
 versions of Cabal (1.2.2.0), HTTP (3001.0.0), and zlib (0.4.0.1) from
 hackage, compile and install cabal-install (0.4.0) from hackage, create a
 directory called dist (to circumvent another problem with cabal-install),
 run cabal update, or cabal install

 os: Linux[[BR]]
 arch: i686[[BR]]
 ghc: 6.6[[BR]]
 zlib: 1.1.4[[BR]]

 Here are the last lines of the output of "ltrace cabal update":
