--- Comment #11 from Mikael Morin <mikael at gcc dot gnu.org> ---
In gfc_conv_expr_descriptor, the bounds used to initialize the descriptor are
different from the ones passed to gfc_get_array_type_bounds.  That is the heart
of the problem, I think.
What I don't understand is how this could remain unnoticed for so long.
