Hmm, if it's v12 then NodeTag 223 is T_List, which is ... a bit
surprising. That's a common enough node type that "oversight"
doesn't seem to fly as an explanation.
I don't think we'll be able to make progress on this without a
lot more detail. A self-contained example that triggers it
would be very useful; or maybe you could get a backtrace from
the point of the error?

A handy trick for similar cases (not mentioned in the wiki) is to set
SET log_error_verbosity = verbose;
and then trigger the error. This logs the exact location (file:line)
where the error is printed, and then set a breakpoint to that place.
Makes it easier to generate the backtrace.
