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?
