    PR fortran/98017 - Suspected regression using PACK

    When substituting a parameter variable of type character, the character
    length was reset to 1.  Fix this by copying the length.

    gcc/fortran/ChangeLog:

            * expr.c (simplify_parameter_variable): Fix up character length
            after copying an array-valued expression.

    gcc/testsuite/ChangeLog:

            * gfortran.dg/pr98017.f90: New test.
