And I narrowed it down: when I replace the leading 0000 hexuplet with
1234, it succeeds. So, leading zeros seem to be the problem. I also tried
to replace instead with a single 0 (thinking redundant leading zeros
might be it) but that still fails.
Doing this now in test 0002 instead from command line. Significantly,
that test didn't try any address with leading zeros before.
