int main() {
    HParseResult* p;
    const uint8_t *input = (const uint8_t*)"\x69\x5A\x6A\x7A\x8A\x9A";

#define MY_ENDIAN (BIT_BIG_ENDIAN | BYTE_LITTLE_ENDIAN)

#undef MY_ENDIAN

    H_RULE(samples, h_sequence(h_repeat_n(sample, 3), h_ignore(h_bits(2, false)), NULL));

    H_RULE(header_ok, h_sequence(nibble, nibble, NULL));

    p = h_parse(parser_weird, input, 6);
    fprintf(stderr, "length:%zu\n", p->bit_length); /* 36 ?! */
    h_parse_result_free(p);
    p = h_parse(parser_ok, input, 6);
    fprintf(stderr, "length:%zu\n", p->bit_length); /* 40 */
    h_parse_result_free(p);

    return 0;
}

This isn't obvious since I reordered the parses from the rules to rule out state corruption, but parser_weird ought to be 4 bits longer, not shorter, than parser_ok.
