 Sorry for the lack of detail. I thought I'd file this upstream. We've been
 seeing this in Ubuntu with 7.4.2. Some cabal packages, like chell, fail to
 build with a segfault in ghc.

 Full build log attached. I'll try to reduce the example and/or reproduce
 with 7.6 soon. (I can also provide you with SSH access to hardware if you
 need it).
