        PR fortran/69128
        * trans.h (OMPWS_SCALARIZER_BODY): Define.
        (OMPWS_NOWAIT): Renumber.
        * trans-stmt.c (gfc_trans_where_3): Only set OMPWS_SCALARIZER_WS
        if OMPWS_SCALARIZER_BODY is not set already, and set also
        OMPWS_SCALARIZER_BODY until the final loop creation.
        * trans-expr.c (gfc_trans_assignment_1): Likewise.
        * trans-openmp.c (gfc_trans_omp_workshare): Also clear
        OMPWS_SCALARIZER_BODY.
        * trans-array.c (gfc_trans_scalarized_loop_end): Don't create
        OMP_FOR if OMPWS_SCALARIZER_BODY is set.

        * gfortran.dg/gomp/pr69128.f90: New test.
