Problem was that verify_constraints() didn't check if there was an error as part of evaluating constraints (can happen in strict mode). In one-row-insert the error was ignored when using binary logging as binary logging clear errors if insert succeeded. In multi-row-insert the error was noticed for the second row. After this fix one will get an error for both one and multi-row inserts if the constraints generates a warning in strict mode.
