Pass more than the first XLogRecData entry to rm_desc, with WAL_DEBUG. If you compile with WAL_DEBUG and enable it with wal_debug=on, we used to only pass the first XLogRecData entry to the rm_desc routine. I think the original assumprion was that the first XLogRecData entry contains all the necessary information for the rm_desc routine, but that's a pretty shaky assumption. At least standby_redo didn't get the memo.
To fix, piece together all the data in a temporary buffer, and pass that to the rm_desc routine. It's been like this forever, but the patch didn't apply cleanly to back-branches. Probably wouldn't be hard to fix the conflicts, but it's not worth the trouble.
