Description Ilya Tikhonovsky 2012-11-20 09:09:46 PST
Our test bot counts pointers which don't match with objects allocated by tcmalloc.
This counter becomes nonzero after instrumenting ActiveDOMObject class.
It happens because it is the base class for many other classes. ~30
And almost all these classes use multiple inheritance.
