    Description

      Cursor and ps protocols because of server design vary the paths taken though the SQL significantly. The UBSAN applies strict testing of the data types passed so a developer cast of the data type may work correctly in a normal mode but fail under protocol.

      An example of this is MDEV-37503 where it was assumed all items where Fields. UBSAN under ps-protocol showed clearly this wasn't the case.

      MDEV-37438 is another example.
