Well, I can't reproduce on my machine. My ppc machine self-hosted fine last night. I think there is something else going on. Stuart, Dale, can one of you guys reproduce this look at this a bit? Is it llvmCore being miscompiled or llvmgcc42? Please get me a test case if that's possible. Thanks.

Dan, can you audit my patch carefully? Thanks.
