Is this a bug in hash.h#81 HashBuffer()?

template <typename T>
PBRT_CPU_GPU inline uint64_t HashBuffer(const T *ptr, size_t size, uint64_t seed = 0) {
    return MurmurHash64A((const unsigned char *)ptr, size, seed);
}

PBRT_CPU_GPU inline uint64_t MurmurHash64A(const unsigned char *key, size_t len,
                                           uint64_t seed) {
    const uint64_t m = 0xc6a4a7935bd1e995ull;
    const int r = 47;

    uint64_t h = seed ^ (len * m);

    const unsigned char *end = key + 8 * (len / 8);

In the function HashBuffer(), the pointer ptr is converted to unsigned char * type, but the size is element size, not byte size. So in MurmurHash64A(), the end is not the real end of the data.
