Hey everyone,<br>
<br>
After I upgraded to a newer cabal-install my cabal-install broke again: I get a Bus Error when doing "cabal update" or "cabal install something". The version that was bundled with the Haskell platform worked fine, but now it's broken again. I'm not sure what it was that went wrong or how to debug this.<br>
</blockquote><div><br>This happened to a co-worker on her mac. We used gdb to track the bus errors to the network library. 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).<br>
<br>I don't think my co-worker has had issues since upgrading to GHC 6.12.<br> <br></div><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">

The previous time I had Bus Errors I upgraded to the newest available Haskell Platform release and started from scratch. I would prefer not to do that again. However, I don't really know how to solve the Bus Error. Does anyone have a clue where to start? Or is there a way to undo my cabal-install upgrade?<br>
</blockquote><div><br>Well, you could try removing $HOME/.cabal (make a backup first?), and then rebuild re-install cabal-install and it's dependencies.<br><br>You might also spend some time running cabal-install inside gdb to see where it's crashing and report back what you find out.<br>
<br>I hope that helps,<br>Jason<br></div></div>
