How old is your 2.2.7 copy?
Until relatively recently, records were not positivity checked at all.
Presumably this was because recursive records weren't intended to be allowed,
but they nevertheless were.
However, the bug has been fixed (by positivity checking, not disabling
recursive records). You may not have rebuilt since it was, though.
