Through pointer mapping sets and fault model, it can detect bad deallocation, memory leak and null pointer dereference faults automatically and increase the testing efficiency.

通过指针映射集和故障模型，可以自动检测内存释放异常、内存泄露和空指针引用等动态内存故障，提高了测试效率。

If there is only a single mapping to the page, then a single pointer called "direct" can be used instead of a linked list.

如果只有一个到这个页的映射，那么可以用一个叫做“direct”的指针来代替链表。
