Suspect its an kernel race condition triggered by ntp bumping the second.

How could I create a test case that reproduces what ntp does? Just add
a second?

I'd think that setting the clock to just before midnight on Dec.31 and using the adjtimex syscall to set the TIME_INS state on the clock, then waiting until midnight rolls around would be a reasonable test..
