It looks like a re-manifestation of Geert's bug.

You said everything worked in -rc7, and there actually have been no sr
changes at all between then and now, so I'm a bit confused as to how it
could reappear.  Could you try a bisection search for it (first
re-verify -rc7 is OK, just in case that's a false negative).
