Hmm ... I see that in PG v13, but not in v14 and up. The fix likely
came from snowball tag v2.0.0 or v2.1.0, which we incorporated during
the v14 cycle. We certainly wouldn't back-patch those whole commits,
and it's hard to get excited about seeing whether it's possible to
tease out a change that would avoid this crash while not changing the
stemmer's semantics. Especially so when v13 is less than a year from
EOL. I'd recommend updating to v14 or later if you need that stemmer.
regards, tom lane
