I just found that in a newer commit (23rd Oct 2019), the problem has been
solved. There's an inline function named "crc64_byte" defined in file
"hashtbl.h". This function seems dealing with the typecasts correctly.

```c
static inline uint64_t crc64_byte(uint64_t crc, uint8_t v)
{
    extern const uint64_t crc64_tab[256];
    return crc64_tab[(uint8_t)(v ^ crc)] ^ (crc >> 8);
}
```
