When one of the pointers is freed, the memory location they both point to is deallocated. The other pointer becomes a dangling pointer, meaning it points to a memory location that has been freed. Attempting to use or free it again can lead to undefined behavior, including run-time errors. Thus, it should be considered uninitialized for practical purposes, and freeing it again can cause errors.
