Thanks for the report, I've been away for a while, thus the late response.
Please update to get this relevant fix and some other TCP fixes (if you
haven't yet):


...If you still get them afterwards, please do rereport (and include me
as recipient :-)). ...I know there are couple of cases still after that
fix where TCP invariant checks trigger but they've been rare enough to
evade any of my debugging attempts ( won't warn you anyway when
it breaks an invariant though I already know a handful violations that
do occur with it too but there's just plain silence because I only later
on added those warning).
