+// NOTE: -fno-integrated-cc1 has been added to work around an ASAN failure
+//       caused by in-process cc1 invocation. Clang InterfaceStubs is not the
+//       culprit, but Clang Interface Stubs' Driver pipeline setup uncovers an
+//       existing ASAN issue when invoking multiple normal cc1 jobs along with
+//       multiple Clang Interface Stubs cc1 jobs together.
