null-terminate some formatted string
Any u8* variable created by format() is NOT null-terminated. Add the null terminating byte with vec_terminate_c_string(). If that variable is used by (at least) hash_get_mem(), then it needs to be null-terminated, as it will go through string_key_sum() which makes a call to strlen.
