| // objects will be treated as a source of live pointers, i.e. any heap objects |
| // reachable by following pointers from an annotated object will not be |
| // reported as leaks. |
| // |
| // ANNOTATE_SCOPED_MEMORY_LEAK: all allocations made in the current scope |
| // will be annotated as leaks. |
| // ANNOTATE_LEAKING_OBJECT_PTR(X): the heap object referenced by pointer X will |
| // be annotated as a leak. |
