Enhance the sqlite3VdbeRecordCompare() routines so that if they encounter
...
database corruption, they will set the UnpackedRecord.isCorrupt field and
return 0. The sqlite3BtreeMovetoUnpacked() routine detects this and returns
SQLITE_CORRUPT, causing the corruption to be reported back to the top-level.
