--- Comment #1 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
This is invalid:
A list item that appears in a reduction clause of a scope construct must be
shared in the parallel region to which a corresponding scope region binds.
We just should diagnose it.

openmp: Disallow reduction with var private in containing parallel even on
scope [PR102504]
The standard has a restriction:
"A list item that appears in a reduction clause of a scope construct must
be
shared in the parallel region to which a corresponding scope region binds."
similar to the restriction for worksharing constructs, but we were checking
it only on worksharing constructs and not for scope and ICEd later on
during
omp expansion.
2021-09-29 Jakub Jelinek <jakub@redhat.com>
PR middle-end/102504
* gimplify.c (gimplify_scan_omp_clauses): Use omp_check_private
even
in OMP_SCOPE clauses, not just on worksharing construct clauses.
* c-c++-common/gomp/scope-4.c: New test.
