    gcc/fortran/ChangeLog:

            * trans-decl.c (convert_CFI_desc): Only copy out the descriptor
            if necessary.
            * trans-expr.c (gfc_conv_gfc_desc_to_cfi_desc): Updated attribu=
te
            handling which reflect a previous intermediate version of the
            standard. Only copy out the descriptor if necessary.

    libgfortran/ChangeLog:

            * runtime/ISO_Fortran_binding.c (cfi_desc_to_gfc_desc): Add code
            to verify the descriptor. Correct bounds calculation.
            (gfc_desc_to_cfi_desc): Add code to verify the descriptor.

    gcc/testsuite/ChangeLog:

            * gfortran.dg/ISO_Fortran_binding_1.f90: Add pointer attribute,
            this test is still erroneous but now it compiles.
            * gfortran.dg/bind_c_array_params_2.f90: Update regex to match
            code changes.
            * gfortran.dg/PR93308.f90: New test.
            * gfortran.dg/PR93963.f90: New test.
