    Fortran: character array constructor with >= 4 constant elements [PR103115]

    gcc/fortran/ChangeLog:

            PR fortran/103115
            * trans-array.cc (gfc_trans_array_constructor_value): If the first
            element of an array constructor is deferred-length character and
            therefore does not have an element size known at compile time, do
            not try to collect subsequent constant elements into a constructor
            for optimization.

    gcc/testsuite/ChangeLog:

            PR fortran/103115
            * gfortran.dg/string_array_constructor_4.f90: New test.
