Do we know from the test thing that it's definitely the last patch
in the series (i.e. the specific one indicated)? That last patch is
the only one with substantive modifications to it, and I wasn't
entirely clear what the original code did (as posted here).

Also do we know how to trigger/replicate this (I'm afraid I don't
know how to read the output).

Stefano had an alternate way of fixing this though it involved un-inlining
something IIRC. Perhaps I should go back and look at that.

Any ideas Stefano?
