   5 //       caused by in-process cc1 invocation. Clang InterfaceStubs is not the
   6 //       culprit, but Clang Interface Stubs' Driver pipeline setup uncovers an
   7 //       existing ASAN issue when invoking multiple normal cc1 jobs along with
   8 //       multiple Clang Interface Stubs cc1 jobs together.
