That is certainly a bug, but there's zero hope of anyone fixing it
without a reproducible test case to poke at.

Looking at our commit log, there was a fix in 17.3 for a problem that
resulted in "unrecognized node type" errors [1], so it'd behoove you to
make sure you are running 17.recent before spending any more effort.
