--- Comment #14 from Martin Sebor <msebor at gcc dot gnu.org> ---
Both Warray-bounds-8 and Wstringop-overflow-3.C pass with the Darwin cross now.
 Both the Darwin cross and a native GCC 10 now also issue the same warnings for
the test case in comment #7.

With the cross I see a bunch of failures in a few other tests (below) but those
should get their own bug(s).
