There's always one more! :-(

Yes, looking now it is. The function that is called from that macro takes a
void *, so I don't think the temporary variable is needed at all. I'll do a
V3, changing ctx_txd to &txr[tx_id] in that instance.
However, compiling with the DUMP_DESC flag turned on raises a whole set of
other compiler warnings in the code - even with 18.08 release. Therefore
that option should either be fixed and made a proper debug option in the
build config, or else dropped.
