        * trans-array.c (gfc_trans_array_bound_check): Take extra argument to
        indicate whether we should check the upper bound in that dimension.
        (gfc_conv_array_index_offset): Check only the lower bound of the
        last dimension for assumed-size arrays.
        (gfc_conv_array_ref): Likewise.
        (gfc_conv_ss_startstride): Likewise.

        * gfortran.dg/bounds_check_7.f90: New test.
