I've not even checked the URLs yet, but since it came up here, I thought I'd ask about it and having gotten a response, here's the gist. (FWIW, I've been running it experimentally for a bit now. No issues with it have I seen, but I've not done a full emerge --emptytree system/world yet.) I'll probably have a bit more to say about it after checking the tinyurls, which at this point I don't even know where they go yet, let alone their content.

I'd say that there's more ICE's on i686-pc-linux-gnu than x86_64-*-linux-gnu, but there's still enough. Luckily Halcy0n was really good for reducing testcases and pushing them upstream, so a lot of these issues got fixed at the source. -- Duncan - List replies preferred. No HTML msgs.
