unit test test_255_bytes_null_end() fails

[danmcb]

test_255_bytes_null_end: Failed, encoded_buffer != expected_buffer. Expected encoded_buffer[255] = 0x00, got 0x01

the test is not actually run in the library, but if you add it into main() you see it fails.

int main(int argc, char*argv[])
{
    printf("testing COBS\n");
    test_single_null();
    test_hex1();
    test_255_bytes_null_end(); // add it here

Is this a problem with test or the library? Investigating.
