Once we tracked it down to there, we did some combination of deleting $HOME/.cabal, building/installing the latest version of Network and then relinking cabal-install. I've also seen these errors with some versions of zlib (but, I think that was on an old Solaris box that had lots of issues). I don't think my co-worker has had issues since upgrading to GHC 6.12. > > The previous time I had Bus Errors I upgraded to the newest available > Haskell Platform release and started from scratch.

You might also spend some time running cabal-install inside gdb to see where it's crashing and report back what you find out. I hope that helps, Jason
