+int comma3[(1, 2)]; // expected-warning {{variable length array folded to

Comment at: clang/test/SemaCXX/warn-unused-value.cpp:145
+namespace test5 {
+int v[(5, 6)]; // expected-warning {{expression result unused}}
+void foo() {
----------------
This is another one that tripped me up due to the diagnostic wording.
