That's fine, no worries.

I have a hunch what it might be. We should clear the BL cache in the deopt-path before calling into inflate_and_enter(), because we might be getting some stale cache entry from the interpreter frame. I'll try this out later (not sure when I get to it, though, I'll be traveling tomorrow).
