Hi Miles,

Okay. Keep me posted.

Just FYI, as mentioned, I'm unable to reproduce this, and you haven't
provided any further minimized guidance on how I might reproduce this,
so it'll sit in the "not a bug" bin until I have another clue on how
to reproduce. Alternatively, Nick and Nathan are now on this thread
and they usually have good luck teasing out compiler issues and such,
so maybe they'll have an idea. But I'm afraid with the information I
currently have, I'm at a dead end.

Jason
