Bus error in Network package

I encountered a bus error when running some HTTP client code in GHC this morning. I've run this code many times before without error and I'm not sure what's changed since then.

I've reduced the problem down to the following example case:

batkins@hudson hsales (master) % ghci
GHCi, version 6.12.3: http://www.haskell.org/ghc/  :? for help

Bus error

Again, it used to work and I'm not sure what's changed since. Here's my ghc --info:

Although I used ghci for the example, this is reproducible in compiled and interpreted code as well.
