--- Comment #6 from Paul Thomas <pault at gcc dot gnu.org> ---
I have spent an hour or so looking at this one.  I think that I can see how to
fix it.  The problem is that expr.c(is_subref_array) is triggering the use of
pointer arithmetic, using the hidden .span variable, when it should not. The
expressions below work fine with array indices.

I just have to sit down and figure out a consistent logic.

Something for next weekend!

Cheers

Paul
