In the link in the first post, the expected data is '\0\1\2\3\4\5' and
the actual data is '\5\4\3\2\1\0'. It looks like a uint48_t written
with the wrong endianness.

Note that test 15 didn't fail in today's build, even though it did fail
for the last four days in a row. There don't seem to have been any
relevant commits yesterday.
