    PR fortran/99205 - Out of memory with undefined character length

    A character variable appearing as a data statement object cannot
    be automatic, thus it shall have constant length.

    gcc/fortran/ChangeLog:

            PR fortran/99205
            * data.c (gfc_assign_data_value): Reject non-constant character
            length for lvalue.
            * trans-array.c (gfc_conv_array_initializer): Restrict loop to
            elements which are defined to avoid NULL pointer dereference.

    gcc/testsuite/ChangeLog:

            PR fortran/99205
            * gfortran.dg/data_char_4.f90: New test.
            * gfortran.dg/data_char_5.f90: New test.
