I'm using debian's gcc-snapshot package, which updates a bit less
frequently than what Fabien does. It'll auto-update as soon as that has
happened.

What disconcerts me a bit is that afaict there wasn't an intentional fix
in the relevant area (disabling value range propagation fixes the
miscompilation), so I'm not quite sure.

Oh, hum. I thought I had. But I did it only for the LLVM enabled
animals. Results should be coming up soon.
