That code looks noticeably different in current upstream, so I suspect
Eggert and crew found and fixed this already. We should probably not
invest brain cells in tracking it down ourselves, but rather
prioritize updating our code to some more-recent tzcode version.
I've been meaning to do that for awhile now, will try to boost it
to the top of my to-do list.
