Strictly speaking, there is no "issue", except that the counter for
"how old is the route?" on your side is being reset every minute.

Packet forwarding works, routing is stable, no CPU churn.

WRT "bugs between different IOS versions" - please read what I wrote
before: frequent reannouncements of a single route *can not* be triggered
by anything on your side.  There is nothing in the BGP protocol which 
would enable this.  (If it happens for *all* routes, it could be a 
soft reconfig request going awry, but this not what you see)
