    PR fortran/93499 - ICE on division by zero in declaration statements

    Division by zero in declaration statements could sometimes
    generate NULL pointers being passed around that lead to ICEs.

    PR fortran/95053 - ICE in gfc_divide(): Bad basic type

            The fix for PR 93499 introduced a too strict check in gfc_divide
            that could trigger errors in the early parsing phase.  Relax the
            check and defer to a later stage.
