        * trans-array.c (gfc_trans_create_temp_array): If n is less
        than the temporary dimension, assert that loop->from is
        zero (reverts to earlier versions). If there is at least one
        null loop->to[n], it is a callee allocated array so set the
        size to NULL and break.
        (gfc_trans_constant_array_constructor): Set the offset to zero.
        (gfc_trans_array_constructor): Remove loop shifting around the
        temporary creation.
        (gfc_conv_loop_setup): Prefer zero-based descriptors if
        possible.  Calculate the translation from loop variables to
        array indices if an array constructor.

        * trans-array.c (gfc_trans_create_temp_array): If size is NULL
        use the array bounds for loop->to.
