-// This is a unittest set for type_profiler.  It is independent from other
-// tests and executed manually like allocator_unittests since type_profiler_map
-// used in type_profiler is a singleton (like TCMalloc's heap-profiler), and
-// it requires RTTI and different compiling/linking options from others
-//
-// It tests that the profiler doesn't fail in suspicous cases.  For example,
-// 'new' is not profiled, but 'delete' for the created object is profiled.
