I'm seeing the same on sparc-sun-solaris2.*, both 32 and 64-bit.
Test results for x86_64-w64-mingw32 and ia64-suse-linux-gnu show the same
failure.
Besides (and probably caused by the same revision), I now get
+XPASS: c-c++-common/Warray-bounds-3.c -std=gnu++14 bug (test for warnings,
line 161)
+XPASS: c-c++-common/Warray-bounds-3.c -std=gnu++17 bug (test for warnings,
line 161)
+XPASS: c-c++-common/Warray-bounds-3.c -std=gnu++98 bug (test for warnings,
line 161)
+XPASS: c-c++-common/Warray-bounds-3.c -Wc++-compat bug (test for warnings,
line 161)
which is also seen on ia64-suse-linux-gnu.
