| 14 // reachable by following pointers from an annotated object will not be | |
| 15 // reported as leaks. | |

| 17 // ANNOTATE_SCOPED_MEMORY_LEAK: all allocations made in the current scope | |
| 18 // will be annotated as leaks. | |
| 19 // ANNOTATE_LEAKING_OBJECT_PTR(X): the heap object referenced by pointer X will | |
| 20 // be annotated as a leak. | |
